drm/i915/hdmi: Add missing intel_pfit_mode_valid() for 4:2:0 also modes

Browse Source 
intel_hdmi_mode_valid() is calling intel_pfit_mode_valid() only
on the first attempt (4:2:0 for "4:2:0 only" modes, 4:4:4 for
everything else). Add the call also for the "4:2:0 also" modes case
so that we actually know the pipe scaler can actually produce the
4:2:0 output.
