Subject: [PATCH v4 02/17] dt-binding: mediatek: Get rid of mediatek,larb for multimedia HW
After adding device_link between the consumer with the smi-larbs,
if the consumer call its owner pm_runtime_get(_sync), the
pm_runtime_get(_sync) of smi-larb and smi-common will be called
automatically. Thus, the consumer don't need the property.
And IOMMU also know which larb this consumer connects with from
iommu id in the "iommus=" property.
