[CI 1/3] drm/xe: Drop ggtt invalidate from display code

[Maarten Lankhorst <maarten.lankhorst@linux.intel.com>]

From: Matthew Brost <matthew.brost@intel.com>

Only buffers mapped in the GGTT used by the GuC require an invalidation.
Display buffers do not require an invalidation. Delete the invalidatio
from display code and make invalidation a static function in xe_ggtt.c.
