This patch needs a bit of a re-think.

You need to be able to unmask and mask an interrupt from a GPIO pin. So it
would be better if the macro took an enable/disable or mask/unmask parameter
and then set a bit in IER or IDR.

You ACK macro makes no sense. You cannot ACK a specific pin. What you have to
do is read the interrupt status for a PIO port, ie 32 pins and then determine
if your pin of interest has generated an interrupt. I cannot think of a way to
do this with macros which is portable across different AT91SAM devices. You
have to write some C code which is specific to your platform.
