GIC: Introduce API to get interrupt ID
Acknowledging interrupt shall return a raw value from the interrupt controller in which the actual interrupt ID may be encoded. Add a platform API to extract the actual interrupt ID from the raw value obtained from interrupt controller. Document the new function. Also clarify the semantics of interrupt acknowledge.
