Extending HDR support for MCA 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: Re-used hsw infoframe write implementation for HDR metadata for LSPCON as per Ville's suggestion. v3: Addressed Jani Nikula's review comments. v4: Addressed Ville's review comments, removed redundant wrapper and checks, passed arguments instead of hardcodings.
