gpioirq(4) version 2
This update makes this driver more than just an example and allows for:
o More than one pin to be attached to a gpioirq instance. That is,
the mask parameter can be greater than 0x01 now.
o A /dev/gpioirqN device that allows GPIO pin interrupts to be
transported into userland. This is a device that can be opened for
reading with a simple fixed output indicating the device unit, pin
number and current pin state.
This update was used as part of a physical intrusion detection system
where multiple switches (i.e. window magnetic reed switches and etc.)
are tied to a bunch of GPIO inputs with userland software that reacts
to the pins changing state.

Add an example "gpioirq" driver that demonstrates interrupts on GPIO
pins. Will be enhanced in the future to support sending events to
user space on edge-triggered interrupt events.
Based on initial work by Brad Spencer.
