[Axel Lin <axel.lin@ingics.com>]

This fixes below build warnings:

  CC      drivers/gpio/gpio-dwapb.o
drivers/gpio/gpio-dwapb.c: In function 'dwapb_configure_irqs':
drivers/gpio/gpio-dwapb.c:258:33: warning: assignment from incompatible pointer type [enabled by default]
  CC      drivers/gpio/gpio-pl061.o
drivers/gpio/gpio-pl061.c:261:2: warning: initialization from incompatible pointer type [enabled by default]
drivers/gpio/gpio-pl061.c:261:2: warning: (near initialization for 'pl061_irqchip.irq_request_resources') [enabled by default]
