This patch fix the wrong reg value for rk322x/rk322xh,
cuz there is no STORE JUSTIFIED MODE on it.
on rk322x/rk322xh, the same bit means PDM_MODE/RESERVED,
if the bit is set to RESERVED, the controller will not work.

This patch marks SPDIF_SMPDR as volatile to make it resaonable,
which also requires marking it as readable, even though it isn't.

When restoring registers during runtime resume, we must not write to
I2S_TXDR which is the transmit FIFO as this queues up a sample to be
output and pushes all of the output channels down by one.
This can be demonstrated with the speaker-test utility:
for i in a b c; do speaker-test -c 2 -s 1; done
which should play a test with through the left speaker three times but if
the I2S hardware starts runtime suspended the first sample will be played
through the right speaker.
Fix this by marking I2S_TXDR as volatile (which also requires marking it
as readable, even though it technically isn't). This seems to be the
most robust fix, the alternative of giving I2S_TXDR a default value is
more fragile since it does not prevent regcache writing to the register
in all circumstances.
While here, also fix the configuration of I2S_RXDR and I2S_FIFOLR; these
are not writable so they do not suffer from the same problem as I2S_TXDR
but reading from I2S_RXDR does suffer from a similar problem.

On RK3399/RK3399Pro platforms, We found that when USB 3.0
read/write at the same time in the following test case,
it may easily fail to transfer data with unknown problem.
Host transfer: 24B, 4MB, 4MB, 4MB
Device transfer : 24B, 4MB, 4MB, 4MB
Both Host and Device transfer "24B, 4MB, 4MB, 4M" Repeatedly
until transfer fail.
This patch adds 150us between the 24B and 4MB data to work
around the transfer issue. This patch may affect the USB 3.0
transmission performance, so we mark it as a HACK. We can
revert this patch if we find the root cause and fix this
issue with more reasonable patches.

Some hardware need to translate scaling list table address to u32
address in register. The dma_addr_t on 64bit kernel will cause
overwriting to later register file.

The rockchip IQ tool uses the data buf of the uvc_request_data
to send vendor specific uvc control data to uvc host, or receive
data from uvc host. The max data payload maybe 4096 bytes, so we
increase the data buf of uvc_request_data to 4096, and also change
the UVC_MAX_REQUEST_SIZE to 4100 correspondingly.

The rockchip IQ tool sends data via usb uvc. The data buf
of v4l2_event is used for IQ tool userspace on uvc device
side to receive vendor specific data from host, the max
length of data maybe 4096 bytes, so increase the data length
of v4l2_event to 4100.
I have already tested the usb host uvc function, it works
well with this patch.
Note:
The userspace need to update the data length of v4l2_event
to 4100 synchronously.
