Looks like coalescing GGTT invalidations is causing issues with the
driver load, just disable this feature during driver load. Also add
module parameter to disable this feature for user space too in case we
suspect this is causing user hangs. 

v2: Initialize module parameter to false

  drm/xe: Always invalidate GGTT on map during driver load
  drm/xe: Add always_invalidate_ggtt module parameter
