After adding device_link between the iommu consumer and smi-larb,
the pm_runtime_get(_sync) of smi-larb and smi-common will be called
automatically. we can get rid of mtk_smi_larb_get/put.

It's possible that there's so little left in mediatek/smi.h that it
could be deleted entirely and its last remaining bits absorbed into
other locations. But maybe it's nice to keep those last little bits
used by mtk-smi.c away from the iommu definitions. So it seems fine
as-is to me.
