The HDMI sink may support different color depths for RGB and/or YUV
colorspaces. Currently, for mscale, 10-bit YUV420 is used only for
2160p@60. For the rest of modes 8-bit RGB is used.
This patch will add a mode_fixup() hook in the hdp_ops struct, allowing
each platform to perform a better handling of the various color depths
and colorspaces.
With the current patch, the RGB output will always be preferred to YUV
colorspaces, given the same color depth, since YUV colorspaces perform
UV subsampling, producing less quality. Also, whenever possible, better
color depth will be preferred (12-bit, 10-bit and, lastly, 8-bit).
The chosen colorspace and color depth will always be based on EDID's
Capability Map Data Block and YUV420 Video Data Block, as well as on
HDMI controller's known clock constraints.

When switching from a 10-bit to an 8-bit color depth, the PHY pixel engine
simply stops functioning correctly 90% of the time. This results in the
HDMI sink not detecting any signal.
This patch will reset the PHY pixel engine after the pipe clocks are ON,
in the bridge enable callback. This will make the pixel engine work
correctly when BPC changes. Resetting the pixel engine before all the pipe
clocks are on, produces no results.

Refer to HDMI 1.4 section 6.5.3, non-zero CD data GCP should send in
deep color mode.
Now, when HDMI work in 24bpp, it will send non-zero CD(0x4 for 24bit)
data GCP to protocol analyzer.
It means current HDMI source is working in “24bit deep color mode”.
But HDMI 1.4 CTS 7-19 required DUT should in “No Deep Color support”.
Protocol analyzer expect received zero CD GCP or no GCP.
Disable GCP when bpp is 24 to pass CTS 7-19.

On mscale, 4K@60 uses YUV420. However, the following commit:
8eeed3553bd1: MLK-18690-1: hdmi: Rewrite hdmi avi infoframe function
moved to using the kernel built-in infoframe creation routine, instead
of Cadence's one, but skipped handling the various colorspace formats.
