drm/amd/display: Set up pixel encoding for YCBCR422 



[Why]
fill_stream_properties_from_drm_display_mode() will not configure pixel
encoding to YCBCR422 when the DRM color format supports YCBCR422 but not
YCBCR420 or YCBCR4444.  Instead it will fallback to RGB.

[How]
Add support for YCBCR422 in pixel encoding mapping.
