lynxpoint: Add interrupt for GPIO controller in ACPI device

The GPIO controller uses IRQ14 as an active high level triggered
source for GPIOs that are configured to trigger shared interrupt.

This was also tested on bolt by configuring the touchscreen to use
a shared GPIO interrupt:

localhost ~ $ grep atmel_mxt_ts /proc/interrupts
54:    24    188    93    124    LP-GPIO-demux    atmel_mxt_ts
