drm/i915: Enable infoframes on GLK+ for HDR
This patch enables infoframes on GLK+ to be used to send HDR metadata to HDMI sink. v2: Addressed Shashank's review comment. v3: Addressed Shashank's review comment. v4: Added Shashank's RB. v5: Dropped hdr_metadata_change check while modeset, as per Ville's suggestion. v6: Removed an unused and duplicate bit defintion, as per Ville's comment.
