drm/msm: update HDMI AVI infoframe during HDR playback

Add support to update the HDMI AVI infoframe to use
BT2020 encoding during HDR video playback.

This is required as per the spec to ensure that the
AVI infoframe correctly indicates the content being
shown.

Also make sure to change and restore the YCC
quantization bits in case of override.
