This commit adds a workaround for the TWAI listen only mode errata which is
present on the ESP32, ESP32-S2, ESP32-S3, and ESP32-C3. twai_get_status_info()
has also been updated to account for the fact that TEC/REC are frozen in
listen only mode.
Errata Description:
When the TWAI controller is put into listen only mode, it should not influence
the TWAI bus in any way (i.e., should never send a dominant bit). However,
on the targets listed above, the TWAI controller will send dominant bits in an
error frame (i.e., active error frame), even if the controller is set to listen
only mode.
Workaround:
We can force the TWAI controller into the error passive state on startup (by
setting the REC to >= 128). Since the TEC/REC are frozen in listen only mode,
the TWAI controller will remain error passive and only send recessive bits
(i.e., passive error frames), thus will not influence the TWAI bus.

1. add check in the gdma driver, to prevent multiple channels connecting
to the same peripheral
2. memory copy DMA ID will occupy the peripheral's DMA ID on some ESP
targets (e.g. esp32c3/s3). We should search for a free one when
install async memcpy driver.

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.
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.
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"
I'm including <hal/uart_ll.h> in my C++ application because I need to
bypass the uart driver. The inline functions in the header file fail to
compile as C++.
All of the enums need explicit casts for conversion to/from integers.
