[PATCH v11 3/5] drm/i915/display: Acomodate format check in intel_plane_can_async_flip()

[Arun R Murthy <arun.r.murthy@intel.com>]

The function intel_plane_can_async_flip() checks for async supported
modifier, add format support check also in the same function.

Note: on ADL the surface base addr is required to be 16k aligned and if
not might generate DMAR and GGTT faults leading to glitches.

v11: Move filtering Indexed 8bit to a separate patch (Ville)
v12: correct the commit msg and remove unwanted debug print (Ville)
