[igt-dev] [PATCH i-g-t] tests/kms_ccs: Use igt_plane_has_format_mod()

[Ville Syrjala]

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

Replace the open coded IN_FORMATS parsing with
igt_plane_has_format_mod() now that we have such a thing.

v2: Remove all the extra cruft too
    Deal with data->ccs_modifier
