drm/i915: Make the DERRMR SRM target global GTT
The ring scratch pages don't have a PPGTT mapping, so the DERRM SRM should target the global GTT instead. v2: Add MI_SRM_LRM_GLOBAL_GTT define for -fixes Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
