The GIC specification describes ID registers in each GIC register frame (PIDRx), which can be used to identify a GIC component. The Arm Ltd. GIC implementations use certain ID values to identify the distributor, the redistributors and other parts like ITSes. Introduce a function that reads those part number IDs, which are spread over two registers. The actual numbers are only meaningful in connection with a certain GIC model, which would need to be checked beforehand, by the caller.
