drm/ttm: split the mm manager init code (v2)
This will allow the driver to control the ordering here better. Eventually the old path will be removed. v2: add docs for new APIs. rename new path to ttm_mem_type_manager_init/set_used(for now) Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200804025632.3868079-14-airlied@gmail.com
