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

The '>' looks weird. For best clarity I would just use
'x == YCBCR444 || x == YCBCR420'

I knew I would get this comment, still gave a try :-), was just trying 
to reduce one if condition, and dint want
to add (x == YCBCR444 || x == YCBCR420) to all the places. Will do the 
changes.
