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.
