[PATCH 1/2] drm/xe: Use fb cached min alignment

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

From: Tvrtko Ursulin <tvrtko.ursulin@igalia.com>

Instead of just looking at the first plane use the fb cached overall
minimum alignment.

This aligns with how the i915 version of intel_plane_pin_fb works.
