For GIC multiple views feature support, all GIC Re-distributor's GICR_TYPER.last will be set. Because configuration view-0 can assign non-contiguous CPUs to views other than 0, in this case the GIC Redistributors' registers won't seem contiguous. So the GIC driver should cope with multiple sets of redistributors like multi-chip scenarios. In this patch we add multiple GIC redistributor regions support in GIC redistributor iteration.
