We should try to get rid of checks that depend on struct
drm_i915_private (or struct xe_device) in display code. HAS_FLAT_CCS()
is one of them. In the interest of simplicity, add a reversed
HAS_AUX_CCS() feature check macro, as that's we mostly use it for in
display.

Is "display < 13 || mtl" good enough?
