Marc Zyngier 89ea8bbe9c gpio: pca953x.c: add interrupt handling capability
Most of the GPIO expanders controlled by the pca953x driver are able to
report changes on the input pins through an *INT pin.

This patch implements the irq_chip functionality (edge detection only).

The driver has been tested on an Arcom Zeus.
