When output colorspace is YCBCR420, we have to load the
corresponding colorspace in AVI infoframe. This patch fills
the colorspace of AVI infoframe as per the output mode.
V2: Rebase
V3: Rebase
V4: Rebase
V5: Added r-b from Ander
V6: Checking RGB/YCBCR420 output only (Ville)
V7: Add colorspace info in driver(not drm layer) (Ville)
V8: Rebase
V9: Added r-b from Ville
