[PATCH i-g-t v2 14/18] tests/kms_ccs: Correctly check clear color for 10bpc formats

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

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

The hardware generated clear color will be in the native
pixel format. Generate the reference correctly for 10bpc
formats.
