When building on arm64 with allmodconfig or CONFIG_DRM_MEDIATEK=m we see
the following error.

  ERROR: modpost: "mtk_mmsys_ddp_disconnect"
  [drivers/gpu/drm/mediatek/mediatek-drm.ko] undefined!
  ERROR: modpost: "mtk_mmsys_ddp_connect"
  [drivers/gpu/drm/mediatek/mediatek-drm.ko] undefined!

Export mtk_mmsys_ddp_connect and mtk_mmsys_ddp_disconnect symbols to be
able to be used for other modules.

Fixes: 396c3fccaf03 ("soc / drm: mediatek: Move routing control to mmsys device")
