Use the new crtc_state member sink_format 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.

I think I'd take this a notch further and start passing
the sink_format to most (maybe even all?) places that
currently take a 'bool ycbcr420_output'. That could also
serve as a slight step towards 4:2:2 support.
Makes sense, will modify the functions as suggested.
