drm/amd/display: add FB_DAMAGE_CLIPS support

Currently, userspace doesn't have a way to communicate selective updates
to displays. So, enable support for FB_DAMAGE_CLIPS for DCN ASICs newer
than DCN301, convert DRM damage clips to dc dirty rectangles and fill
them into dirty_rects in fill_dc_dirty_rects().
