gpio: Add IRQ support to ACCES 104-IDIO-16 driver
The ACCES 104-IDIO-16 series offers Change-of-State detection interrupt functionality; if Change-of-State detection is enabled, an interrupt is fired off if any input line changes state (i.e. goes from low to high, or from high to low). This patch adds support to handle these interrupts and allows the user to mask which GPIO lines are affected. The interrupt line number for the device may be set via the idio_16_irq module parameter.
