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. v4: Addressed Chris and Ville's review comments, and created a common colorspace property for DP and HDMI, filtered the list based on the colorspaces supported by the respective protocol standard. Handle the default case properly. v5: Merged the DP handling along with platform colorspace handling as per Shashank's comments. v6: Reverted to old design of exposing all colorspaces to userspace as per Ville's review comment v7: Fixed a checkpatch complaint, Addressed Maarten' review comment, updated the RB from Maarten and Jani's ack.
