The decision to use DFP output format conversion capabilities should be during compute_config phase. This patch adds new member to crtc_state to represent the final output_format to the sink. In case of a DFP this can be different than the output_format, as per the format conversion done via the PCON. This will help to store only the format conversion capabilities of the DP device in intel_dp->dfp, and use crtc_state to compute and store the configuration for color/format conversion for a given mode. v2: modified the new member to crtc_state to represent the final output_format that eaches the sink, after possible conversion by PCON kind of devices. (Ville) v3: Addressed comments from Ville: -Added comments to clarify difference between sink_format and output_format. -Corrected the order of setting sink_format and output_format. -Added readout for sink_format in get_pipe_config hooks.
