This one can be nuked entirely as Jani pointed out.

Hmm. Technically we only need this for eDP (no 4:2:0
on gmch so that part is irrelevant), but I suppose
there should be no real harm in calling it
unconditionally as gmch_panel_fitting() will check
whether pipe_src matches the mode.

This too can be nuked since there is no 4:2:0 support
on gmch platforms.
