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.

A typical value is 2.8.
Previous commit 32ef2b321aac317bdf6d088ec87c809ab8471042 doesn't fix the issue cleanly. The MSB of wafer_minor also has this problem.
Similar to the fix in gpio lower layers, USB Serial JTAG pad should be disabled when the DM and DP pins want to be used as rtcio pins.
(cherry picked from commit de0401047c478816bc874699368632f53f86f6fa)
In previous gpio default isr, interrupt status bits get cleared at the exit of the isr.
However, for edge-triggered interrupt type, the interrupt status bit should be cleared before entering the per-pin handlers to avoid any potential interrupt lost.
