[PATCH v2] drm/i915/display: add HAS_AUX_CCS() feature check

[Jani Nikula <jani.nikula@intel.com>]

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.

v2: include adl-p (Ville)
