of/iommu: Make of_map_rid() PCI agnostic
There is nothing PCI specific (other than the RID - requester ID)
in the of_map_rid() implementation, so the same function can be
reused for input/output IDs mapping for other busses just as well.
Rename the RID instances/names to a generic "id" tag.
No functionality change intended.
