drm/ttm: add ttm_resource_fini v2
Make sure we call the common cleanup function in all implementations of the resource manager. v2: fix missing case in i915, rudimentary kerneldoc, should be filled in more when we add more functionality Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20220124122514.1832-2-christian.koenig@amd.com
