drm/i915/dp: Configure PCON for conversion of output_format to YCbCr444 



Handle the case with DP to HDMI PCON, where sink_format is set to YCbCr444.
In that case PCON is required to be configured to convert from given
output_format to YCbCR444.

v2: Drop drm_WARN for invalid case, let MISSING_CASE catch it. (Ville)
