From: Yongqiang Niu <redacted> Prepare for smi cleaning up "mediatek,larb". Display use the dispsys device to call pm_rumtime_get_sync before. This patch add pm_runtime_xx with ovl and rdma device whose nodes has "iommus" property, then display could help pm_runtime_get for smi via ovl or rdma device.
