We have plenty drivers in drm without hw mmu, and yeah there's probably no
reason at all why the drm subsystem has a hard depency on cpu MMUs. Might
be some #ifdef fallout that needs to be done, but there shouldn't be
anything fundamental. Maybe the old dri1 days code has something, but
that's all historical cruft anyway.
