MIPS: ath79: fix GPIO function selection for AR934x SoCs
GPIO function selection is not working on the AR934x SoCs because the offset of the function selection register is different on those. Add a helper routine which returns the correct register address based on the SoC type, and use that in the 'ath79_gpio_function_*' routines.
