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.
