  1. bcm_2708: don't use ARCH_NR_GPIOS 

    bcm2708_gpio.c claims all gpios up to ARCH_NR_GPIOS this is a bug as the SoC
only has 54 gpio pins and claiming all gpios prevents other drivers registering
any additional gpios.

Move the driver over to using BCM_NR_GPIOS instead

  1. bcm2708: allow gpio interrupts to actually work 

    gpio_to_irq is provided as a generic function by gpiolib now, so we must
override it with our own version to prevent an infinite recursive loop
