As said on the IOMMU commit, I think that apusys-power can be passed as a
power domain here as well... also keeping in mind that the apuspm power
domain is being used in both the IOMMU and in apusys-power already, so you
could even pass only the apusys-power pd here, because apuspm would be
already being turned on by the former...
...unless there's any possibility to have some functionality with apuspm up
but apusys-power down? From how it looks right now, that's not a thing.

This is supposed to be "mediatek,rpmsg-name" instead... or it won't work.
