[SPLIT UP] gpu: drm: avoid highmem allocations

There is no real need to have any of the DRM allocations backed by
highmem, so change all the GFP_HIGHUSER and GFP_HIGHUSER_MOVABLE
zones to GFP_USER.

This needs to be split up further to give individual reasons
for each one. Some of these probably fix actual bugs, others
may make the behavior slightly worse on systems with little
lowmem.
