This patch adds support for YCBCR 4:4:4 CRTC output format.
To do this, this patch extends the existing YCBCR 4:2:0
framework by:
- Adding new parameter in for YCBCR 4:4:4 enum crtc_iutput_format.
- Adding case for YCBCR 4:4:4 in while setting AVI infoframes.
- Adding necessary checks in modeset sequence.
V3: Added this patch in the series
V4: Added r-b from Maarten (for v3)
Addressed review comment from Ville:
Do not use (config->output_format > CRTC_OUTPUT_RGB)
V5: Rebase
