[PATCHv2] Add GPIO driver for Allwinner SoCs

[Maxime Ripard]

Hi,

This patch adds support for the GPIOs for the Allwinner SoCs supported so
far.

It comes on top of my previous pinctrl patchset, and has been tested on a
A13-Olinuxino from Olimex.

Thanks,
Maxime

Changes from v1:
  - Merged the gpio driver with the pinctrl one
  - Now using gpiochip_add_pin_range instead of pinctrl_add_gpio_range
  - Removed the hairy range registration function, and register 1pin ranges
    instead
