[Intel-gfx] [PATCH v2 6/9] drm/i915/dp: Use crtc_state members in dp_is_ycbcr420

[Ankit Nautiyal]

Use the new crtc_state members to check if DP DFP will use YCBCR420.
The earlier intel_dp->dfp members are not required as decision to use
color format conversion by the PCON is computed and stored in
crtc_state. Also drop the intel_dp argument in the helper function.
