[Intel-gfx] [PATCH v4 14/15] drm/i915: set colorspace for ycbcr outputs

[Shashank Sharma]

When HDMI output is other than RGB, we have to load the
corresponding colorspace of output mode. This patch fills
the colorspace of AVI infoframe as per the HDMI output mode.

V2: Rebase
V3: Rebase
V4: Rebase
