ArmPkg/ArmGic: Returned the InterruptId in ArmGicAcknowledgeInterrupt()
The InterruptId has a different width for GicV2 and GicV3 (respectively 10bit and 24bit). The function prototype has been changed to return this value to make the caller GIC architecture version independent. Otherwise, we would have need to expose a different mask to allow the caller to retrieve this value from the read register.
