ARM: 5817/1: SA1100: h3100/h3600: configure all unused gpios as inputs
After conversion to gpiolib there's still some GPIOs left, that get configured in *_mach_init() as outputs (using direct operations on GPCR/GPDR registers), but otherwise unused. These GPIOs are mainly sound related and should be configured by corresponding driver once it is written. Drop this initialisation and configure all GPIOs as input.
