Alban Bedel 2ddf3a7922 MIPS: ath79: Add OF support to the GPIO driver
Replace the simple GPIO chip registration by a platform driver
and make ath79_gpio_init() just register the device.

Gabor Juhos f818ca3e68 MIPS: ath79: add GPIO setup code for the QCA955X SoCs
The existing code can handle the GPIO controller of
the QCA955x SoCs. Add a minimal glue code to make it
working.

Gabor Juhos f160a289e0 MIPS: ath79: simplify ath79_gpio_function_* routines
Make ath79_gpio_function_{en,dis}able to be wrappers
around ath79_gpio_function_setup.

Gabor Juhos 8838becdf5 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.
