72f00d7c6d feat(usb/host): Update ISOC scheduler for HS endpoints
USB-OTG uses 'sched_info' field of HCTSIZ register to schedule transactions
in USB microframes.

d00aaf8648 refactor(soc/host): Update USB OTG struct fields
This commit updates the "*_struct.h" files for the USB OTG peripheral:

- Added/removed some missing/non-existing register fields
- Added "reserved" place holders for registers that are missing due to IP
configuration.
- Added "usb_dwc_cfg.h" listing the USB OTG IP configuration for each target.
- Updated LL/HAL according to register field updates. Also tidied up the include
directives in those headers.

39d57f1cfd refactor(usb/host): Move FIFO size configuration to HAL layer
The logic of calculating FIFO sizes is DWC OTG specific.
We move it to the HAL layer to provide better abstraction in the HDC layer.

c0de14d0b9 refactor(hal/usb_dwc): Add DWC OTG configuration values
This commit adds a subset of the DWC OTG configuration values to the
'usb_dwc_ll.h' file. Only relevant configuration values have been added.

Some DWC OTG releated constants have also been moved from 'usb_dwc_hal.h'
to 'usb_dwc_ll.h' and renamed.

d69d1aafaf hal: Fix USB DWC HAL host channel halt race condition
This commit fixes a race condtion bug with usb_dwc_hal_chan_request_halt()
where a channel the channel is halted if it has just completed a transfer
(i.e., finished processing a QTD with the "HOC" flag set) but the channel is
still pending interrupt handling. In this case...

- usb_dwc_hal_chan_request_halt() would simply read the channel's underlying
register, determine it is not active, not set the "halt_requested" flag, and
simply return true.
- The caller assumes of usb_dwc_hal_chan_request_halt() will assume that the
channel has halted, and may proceed to reconfigure the pipe/port
- When usb_dwc_hal_chan_decode_intr() comes to process the pending interrupt
it will simply return USB_DWC_HAL_CHAN_EVENT_CPLT not knowing a halt has been
requested.

This commit updates the implementation of usb_dwc_hal_chan_request_halt() so
that a halt is properly requested even if the underlying channel has already
physically halted.

d333833f59 usb_host: Rename struct/ll/hal symbols to use "usb_dwc" prefix
Following the file renaming to use the "usb_dwc" prefix, this commit
updates the symbol names of those files to use the "usb_dwc" as well.

Some LL functions were also renamed so that the register name is
mentioned.

d8d4e3acb0 usb_host: Rename struct/ll/hal files to use "usb_dwc" prefix
This commit updates the DWC_OTG based struct/ll/hal file names to
use the prefix "usb_dwc". This naming scheme reduces ambiguity if
another USB controller implementation is added.

As a result, "hcd.c" has been renamed to "hcd_dwc.c"
