The ar71xx GPIO driver only uses 0x24 registers, all following GPIO registers are using to control pinmux functions, which are not handles by the GPIO driver but the generic Linux pinctrl driver. For some SoC conflicting address ranges were defined for these (AR7240 & AR9330). Resolve these cases and align the address space of the GPIO controller between all SoCs, as the used address space of the driver is identical for all these.
