drm/amdgpu: Wire up MMIO_REMAP placement and User-visible strings
Wire up the conversions and strings for the new MMIO_REMAP placement:
* amdgpu_mem_type_to_domain() maps AMDGPU_PL_MMIO_REMAP -> domain
* amdgpu_bo_placement_from_domain() accepts the new domain
* amdgpu_bo_mem_stats_placement() and amdgpu_bo_print_info() report it
* res cursor supports the new placement
* fdinfo prints "mmioremap" for the new placement
