22c152c388 usb: Hub Driver and USBH recover port automatically after disconnection
This commit updates the Hub Driver and USBH as follows:
- Updated communication mechanism between Hub Driver and USBH
    - USBH notifies the Hub Driver via Hub request callback (usbh_hub_req_cb_t)
    - Hub Driver notifies the USBH via usbh_hub_pass_event()
- Hub Driver now defers all event handling to hub_process.
- Hub Driver and USBH will now automatically recover the port after a disconnected
    device has been closed.
- Fixed incorrect assert in usbh_dev_close()

1aad12468a usb: Hub Driver Update and Refactor
Hub Driver is refactored as follows:

This commit update and refactors the Hub Driver as follows:

- Refactored enumeration state machine and stage functions
    - Enumeration stage is now incremented
    - Combined transfer stages of enumeration into common functions
- Comments updated
- Fixed usbh_hal_disable_debounce_lock() that would cause root_port_handle_events()
    to fail the HCD_PORT_CMD_RESET call because the previous port connection interrupt
    was not cleared.

The following features were added to the Hub Driver

- Enumeration config descriptor is now fetched in two separate stages
    - Header is fetched first to determine the wTotalLength of the descriptor
    - Fetching the full descriptor will request exactly wTotalLength bytes
    - This works around some non-compliant devices that will babble/return zero
        when requesting a length > wTotalLength
    - Closes https://github.com/espressif/esp-idf/issues/7799
- Enumeration now stores string descriptors
    - The Manufacturer, Product, and Serial Number string descriptors are
        now read and stored during enumeration
    - String descriptors are now part of usb_device_info_t
- Added unit test to test enumeration

854127a57c usb: USB Host stack uses USB PHY driver
This commit updates the USB Host stack to use the USB PHY driver. The
USB PHY and the OTG Controller should now both be setup/deleted using
usb_new_phy() and usb_del_phy() respectively.

- The hcd_install() now expects the USB PHY and OTG Contorller to be
    already setup before it is called
- usb_host_install() now has an option to skip calling usb_del_phy() if
    the user wants to setup their own USB PHY (e.g., in the case of using
    and external PHY).
- CDC-ACM and MSC examples/test updated to use internal PHY

5a2ef15565 usb: HCD multiple fixes
This commit fixes the following bugs in the HCD

- HCD control pipes fill incorrect transfer size

_buffer_fill_ctrl() would fill the transfer descriptors length with
wLength instead of transfer->num_bytes. Therefore, the remaining length
would be incorrect when a control transfer requests more bytes than are
available.

- Fix USB_TRANSFER_FLAG_ZERO_PACK behavior

The previous behavior of USB_TRANSFER_FLAG_ZERO_PACK was incorrect, and did not
support interrupt pipes. A zero length packet can now be added to Bulk/Interrupt
OUT transfers where the length is a multiple of the endpoint's MPS.

- Fixed HCD port suspend and resume test case

Halting a control pipe mid control transfer can lead some test devices to get stuck

16677b0d3c global: make periph enable/disable APIs private
peripheral enable/disable usually should be managed by driver itself,
so make it as espressif private APIs, not recommended for user to use it
in application code.
However, if user want to re-write the driver or ports to other platform,
this is still possible by including the header in this way:
"esp_private/peripheral_ctrl.h"

189899180f usb: Change API and refactor tests
This commit updates the USB Host Library API in the following wasy:
- usb_host_client_handle_t and usb_device_handle_t made into struct pointers
  to generate compiler warnings about conflicting handle types
- usb_host_client_config_t changed to future proof API for Synchronous Clients
- Added usb_host_lib_unblock()
- Added usb_host_device_addr_list_fill()
- Return of usb_host_device_free_all() updated to indicate whether there
  are still devices yet to be freed.
- Blockg APIs are now marked explicitly
- Fixed a bug in usb_host_transfer_submit_control() when checking the bEndpointAddress
  of a control transfer.

Tests are also refactored to move some common macros into shared headers

6a12e28333 usb: Fix USBH handling of disconnections
This commit fixes how the USBH handling of a sudden device disconnection,
more specifically handling of device gone.
- Previously the USBH would only halt, flush, and dequeue the device's
default EP, then send a device gone event to the Host Library layer.
- Now the USBH will also halt and flush all non-default EPs, allowing
all of the URBs to be dequeud.
- Some internal object members are now protected by a mutex instead of
a spinlock.

0c758c8557 usb: Fix how the HCD handles sudden disconnection
This commit fixes how the USB Host HCD handles sudden disconnections.

Bugs:
- HW channels remain active when the port suddenly disconnects, and
previously the channel would be disabled by setting the disabled bit,
then waiting for a disabled interrupt. However, ISOC channels do not
generate the disabled interrupt when the port is invalid, thus leading
to tasks getting indefinitely blocked in hcd_pipe_command().

Fix:
On a sudden disconnection, forcibly treat all channels as halted even
if their HCCHAR.ChEna bit is still set. We do a soft reset after a port
error anyways, so the channels will eventually be reset.

accbaee57c Add USB Host Library
This commit adds the preliminary version of the USB Host Library. This commit contains:

- USBH (USB Host Driver)
- Hub Driver that only supports a single device and device enumeration
- USB Host Library (asychronous API)
- Test cases for USB Host Library asychronous API

The following changes were made to the existing HCD:
- Removed HCD_PIPE_STATE_INVALID. Pipes are no longer invalidated
- Changed pipe commands to halt, flush, and clear. Pipes need to be manually
  halted, flush, and cleared.
- Halting and flushing a pipe will execute the pipe callback if it causes a
  HCD_PIPE_EVENT_URB_DONE event

18f9dabce1 USB: Change IRP to URBs
This commit changes the IRP (I/O Request Packet) structure to
the URB (USB Request Block) in order to represent USB transfers
in the host stack. The new URB strcuture:

- Add extra safety with const fields
- Allows each layer of the stack to add their own overhead variables

The HCD layer API and tests have been updated to use this new URB structure
