[Intel-xe] [PATCH 1/9] drm/i915/display: Revert all before remaining changes to make xe compile

[Maarten Lankhorst]

From: Maarten Lankhorst <dev at lankhorst.se>

    drm/xe/display: Allow scanout of bos that can be migrated to lmem
    drm/i915/display: Use intel_bo_to_drm_bo instead of obj->base

Can probably be slightly ignored by squashing with next patch, at least
for intel_bo_to_drm_bo part.

Signed-off-by: Maarten Lankhorst <dev at lankhorst.se>
