GPIO Ports A, B, and F on the ep93xx provide interrupt capability. It is possible to debounce the input signal on these ports when interrupts are enabled. Support for this debounce capability was provided with an ep93xx internal function. Now that gpiolib knows about gpio debounce, use the gpiolib method and do not export the internal function.
