drm/amd/display: Set up pixel encoding for YCBCR422
[ Upstream commit 5e76bc677cb7c92b37d8bc66bb67a18922895be2 ]
[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.
