[PATCH i-g-t 20/23] tests/kms_plane: Extract skip_format_mod()

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We have a few different cases why format/modifier combos
need to be skipped. Pull the code to determine that into
a helper.

This also gives better debug logging for the msm UBWC case,
as previously there was none.
