Arduino functions implemented:
* attachInterrupt(Arduino_Pin, handler, mode):
* it works for all Arduino GPIO (IO0 - IO19)
* CHANGE mode is supported only for SoC GPIOs (hardware limitation:
SS doesn't support interrupt generation on both rising and falling
edges.)
* detachInterrupt()
* interrupts()
* noInterrupts()
Above functions behaviour is according to Arduino website description.
For details please see below references:

This implementation uses ss_gpio and soc_gpio drivers from thunderdome.
