From: Matt Roper <matthew.d.roper@xxxxxxxxx> Since Xe2LPD technically has FlatCCS, it doesn't have AuxCCS registers like PLANE_AUX_DIST. However we currently have HAS_FLAT_CCS hardcoded to 0 since compression isn't ready; we need to make sure this doesn't cause the display code to go back to trying to write this register.
