For the write channels with 4:2:0 subsampled YUV formats, avoid chroma
overdraw by only writing chroma for even lines (skip odd chroma rows).
This reduces necessary write memory bandwidth by at least 25% (more
with rotation enabled).

Only providing the input and output RGB/YUV space to the IC task init
functions is not sufficient. To fully characterize a colorspace
conversion, the Y'CbCr encoding standard, and quantization also
need to be specified.
Define a 'struct ipu_ic_colorspace' that includes all the above.
This allows to actually enforce the fact that the IC:
- can only encode to/from YUV and RGB full range. A follow-up patch will
remove this restriction.
- can only encode using BT.601 standard. A follow-up patch will add
Rec.709 encoding support.
The determination of the CSC coefficients based on the input/output
'struct ipu_ic_colorspace' are moved to a new exported function
ipu_ic_calc_csc(), and 'struct ic_csc_params' is exported as
'struct ipu_ic_csc_params'. ipu_ic_calc_csc() fills a 'struct ipu_ic_csc'
with the input/output 'struct ipu_ic_colorspace' and the calculated
'struct ic_csc_params' from those input/output colorspaces.
The functions ipu_ic_task_init(_rsc)() now take a filled 'struct
ipu_ic_csc'.
The existing CSC coefficient tables and ipu_ic_calc_csc() are moved
to a new module ipu-ic-csc.c. This is in preparation for adding more
coefficient tables for limited range quantization and more encoding
standards.
The existing ycbcr2rgb and inverse rgb2ycbcr tables defined the BT.601
Y'CbCr encoding coefficients. The rgb2ycbcr table specifically described
the BT.601 encoding from full range RGB to full range YUV. Table
comments have been added in ipu-ic-csc.c to make this more clear.
The ycbcr2rgb inverse table described encoding YUV limited range to RGB
full range. To be consistent with the rgb2ycbcr table, this table is
converted to YUV full range to RGB full range, and the comments are
expanded in ipu-ic-csc.c.
The ic_csc_rgb2rgb table was just an identity matrix, so it is renamed
'identity' in ipu-ic-csc.c.

We use delayed_work in HPD handling, and cancel any scheduled work in
tfp410_fini using cancel_delayed_work_sync(). However, we have only
initialized the delayed work if we actually have a HPD interrupt
configured in the DT, but in the tfp410_fini, we always cancel the work,
possibly causing a WARN().
Fix this by doing the cancel only if we actually had the delayed work
set up.

CEA-861 says: "A Source shall not send a non-zero Q value that does
not correspond to the default RGB Quantization Range for the
transmitted Picture unless the Sink indicates support for the Q bit
in a Video Capabilities Data Block."
Make TDA998x compliant by using the helper to set the quantisation
range in the infoframe, and using the TDA998x's colour scaling to
appropriately adjust the RGB values sent to the monitor.
This ensures that monitors that do not support the Q bit are sent
RGB values that are within the expected range. Monitors with
support for the Q bit will be sent full-range RGB.

TDA998x has no support for pixel repeated modes, and the code notes this
as a "TODO" item. The implementation appears to be relatively simple,
so lets add it.
We need to calculate the serializer clock divisor based on the TMDS
clock rate, set the repeat control, and set the serializer pixel
repeat count. Since the audio code needs the actual TMDS clock,
record that.

tda998x_configure_audio() is called via some paths where an error
return is meaningless, and as a result of moving the audio routing
code, this function no longer returns any errors, so let's make it
void. We can also make tda998x_write_aif() return void as well.
tda998x_configure_audio() also only ever needs to write the current
audio settings, so simplify the code in tda998x_audio_hw_params()
so that can happen.

The TDA998x derives the CTS value using the supplied I2S bit clock
(ACLK, in TDA998x parlence) rather than 128·fs. TDA998x uses two
constants named m and k in the CTS generator such that we have this
relationship between the I2S source ACLK and the sink fs:
128·fs_sink = ACLK·m / k
Where ACLK = aclk_ratio·fs_source.
When audio support was originally added, we supported a fixed ratio
of 64·fs, intending to support the Kirkwood I2S on Dove. However,
when hdmi-codec support was added, this was changed to scale the
ratio with the sample width, which would've broken its use with
Kirkwood I2S.
We are now starting to see other users whose I2S blocks send at 64·fs
for 16-bit samples, so we need to reinstate the support for the fixed
ratio I2S bit clock.
This commit takes a step towards supporting these configurations by
selecting the CTS_N register m and k values based on the bit clock
ratio. However, as the driver is not given the bit clock ratio from
ALSA, continue deriving this from the sample width. This will be
addressed in a later commit.
