This will help enable BT2020 along with other colorspaces. v2: Addressed Maarten and Ville's review comments. Enhanced the colorspace enum to incorporate both HDMI and DP supported colorspaces. Also, added a default option for colorspace. v3: Removed Adobe references from enum definitions as per Ville, Hans Verkuil and Jonas Karlman suggestions. Changed Default to an unset state where driver will assign the colorspace is not chosen by user, suggested by Ville and Maarten. Addressed other misc review comments from Maarten. Split the changes to have separate colorspace property for DP and HDMI.

Based on colorspace change, modeset will be triggered to switch to new colorspace. Based on colorspace property value create an infoframe with appropriate colorspace. This can be used to send an infoframe packet with proper colorspace value set which will help to enable wider color gamut like BT2020 on sink. This patch attaches and enables HDMI colorspace, DP will be taken care separately. v2: Merged the changes of creating infoframe as well to this patch as per Maarten's suggestion. v3: Addressed review comments from Shashank. Separated HDMI and DP colorspaces as suggested by Ville and Maarten.
