drm/cirrus: Invalidate page tables when pinning a BO
This is a cirrus version of Egbert Eich's patch for mgag200.
Without bo.bdev->dev_mapping set, the ttm_bo_unmap_virtual_locked
called from ttm_bo_handle_move_mem returns with no effect. If any
application accessed the memory before it was moved, it will
access wrong memory next time. This causes crashes when changing
resolution down.
