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.
