This DWC2 driver has handled the unaligned DMA address problem
for urb->transfer_buffer and split in transfer. But it still
has problem to handle the isoc out transfer with unaligned DMA
address.
I test an USB Audio device which supports 24bits 96KHz 3LE format:
usb 1-1: new full-speed USB device number 2 using dwc2
usb 1-1: New USB device found, idVendor=21b4, idProduct=0083, bcdDevice= 1.06
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1: Product: AudioQuest DragonFly Black v1.5
usb 1-1: Manufacturer: AudioQuest
usb 1-1: SerialNumber: AQDFBL0100023815
When play 24bits 96KHz WAV file, noise occurs.
The rootcause is that the DWC2 controller use internal DMA to
transfer USB audio data, and the DMA address of data buffer must
be 4 bytes aligned, otherwise, the dwc2 will fail to transfer the
data. In this test case, the USB audio may transfer 572 bytes or
582 bytes in one usb transaction. And one URB contains multiple
usb transactions, if the DWC2 transfer the 582 Bytes in the middle
of the URB, the DMA address will not be 4 bytes aligned.
This patch allocates new aligned buf for isoc out transfer with
unaligned DMA address.
For isoc split out transfer, this patch sets the start schedule at
the 2 * DWC2_SLICES_PER_UFRAME to transfer the SSPLIT-begin OUT
transaction like EHCI controller. Without this patch, the SSPLIT-begin
OUT transaction starts in the seventh microframe, and this makes the
USB HUB unhappy. This patch sets the the SSPLIT-begin OUT transaction
starts in the first microframe.

The dwc3 initializes all of the endpoints in the following order:
epnum 0: USB EP0-OUT
epnum 1: USB EP0-IN
epnum 2: USB EP1-OUT
epnum 3: USB EP1-IN
...
This initialization logic works well if the number of IN endpoints
is equal to OUT endpoints. However, some SoCs have different number
of endpoints between the EP-IN and EP-OUT (e.g. RK3399/RV1109 7 IN
endpoints and 6 OUT endpoints), it will fail to init all of the
endpoints in this case.
This patch fixes the initialization logic for all of the IN and OUT
endpoints.
In addition, this patch also fixes the fifo depth of the Tx fifo0
when resize all of the tx fifos. And increase the fifos of isoc IN
endponits to hide system high bus latency.

This patch only clears the unmask interrupts to avoid trigger
unknown Channel Halted interrupt. However, if the Channel Halted
interrupt happens unexpected, we need to check if the urb->length
is 4-byte alignment in dwc2_update_urb_state_abn(), this can help
to avoid the above warning.
