irqchip/mvebu-gicp: Use resource_size() for ioremap()
0-day reported an off by one in the ioremap() sizing:
drivers/irqchip/irq-mvebu-gicp.c:240:45-48: WARNING:
Suspicious code. resource_size is maybe missing with gicp -> res
Convert it to resource_size(), which does the right thing.
Fixes: 3c3d7dbab2c7 ("irqchip/mvebu-gicp: Clear pending interrupts on init")
