brcm63xx: implement gpio_to_irq for bcm63xx-gpio
Add support for mapping some GPIO lines to IRQs. GPIO to IRQ mappings were found out through experimentation, helped by having the GPIO as output still toggling the IRQ input. Based-on: http://patchwork.ozlabs.org/patch/660534/ Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com>
