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.
