Patch adds macros to unmask & acknowledge gpio interrupts

This patch adds macros to unmask & acknowledge gpio interrupts , As said in

GPIO interrupts must be unmasked by setting IMR (interrupt mask register) for
getting interrupts & acknowledged by reading ISR (interrupt status register) of
PIO controller.
