[Intel-gfx] [PATCH v2 4/9] drm/i915/display: Add new members to configure PCON color conversion

[Ankit Nautiyal]

The decision to use DFP output format conversion capabilities should be
during compute_config phase.

This patch adds new members to crtc_state to help configure the DFP
output related conversions. Also adds a member to intel_dp to store
ycbcr420 pass through capability.

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.
