Extending HDR support for MCA and Parade LSPCON based GEN9 devices. SOC will drive LSPCON as DP and send HDR metadata as standard DP SDP packets. LSPCON will be set to operate in PCON mode, will receive the metadata and create Dynamic Range and Mastering Infoframe (DRM packets) and send it to HDR capable HDMI sink devices. v2: Fixed Ville's review comments. Suppressed some warnings. Patch 8 of the series is marked "Not for Merge" and is just for reference to userspace people to incorporate in order to support 10bit content with 4K@60 resolutions. v3: Added Infoframe readout support for DRM infoframes. Addressed Jani Nikula's review comments. Note: Patch 8 of the series is for reference to userspace, not to be merged to driver.
