All the consumer connect with smi-larb, then connect with smi-common.
When the consumer works, it should enable the smi-larb's power which also
need enable the smi-common's power firstly.
Thus, Firstly, use the device link connect the consumer and the
smi-larbs. then add device link between the smi-larb and smi-common.
After adding the device_link, then "mediatek,larb" property can be removed.
the iommu consumer don't need call the mtk_smi_larb_get/put to enable
the power and clock of smi-larb and smi-common.
Base on the media branch [1] and a jpeg dtbinding patchset[2] that already got
the necessary R-b.
