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: 3c3d7dba ("irqchip/mvebu-gicp: Clear pending interrupts on init")
