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.
