In order to readout DP SDPs (Secondary Data Packet: DP HDR Metadata Infoframe SDP, DP VSC SDP), it refactors handling DP SDPs codes. It adds new compute routines for DP HDR Metadata Infoframe SDP and DP VSC SDP. And new writing routines of DP SDPs (Secondary Data Packet) that uses computed configs. New reading routines of DP SDPs are added for readout. It adds a logging function for DP VSC SDP. When receiving video it is very useful to be able to log DP VSC SDP. This greatly simplifies debugging. In order to use a common VSC SDP Colorimetry calculating code on PSR, it uses a new psr vsc sdp compute routine.
v2: Minor style fix v3: - Add a new drm data structure for DP VSC SDP - Replace a structure name to drm_dp_vsc_sdp from intel_dp_vsc_sdp - Move logging functions to drm core [Jani N] And use drm core's DP VSC SDP logging function - Explicitly disable unused DIPs (AVI, GCP, VS, SPD, DRM. They will be used for HDMI), when intel_dp_set_infoframes() function will be called.
