gpio: introduce gpio-mvebu driver for Marvell SoCs
This driver aims at replacing the arch/arm/plat-orion/gpio.c driver,
and is designed to be compatible with all Marvell EBU SoCs: Orion,
Kirkwood, Dove, Armada 370/XP and Discovery.
It has been successfully tested on Dove and Armada XP at the moment.
Compared to the plat-orion driver, this new driver has the following
added benefits:
*) Support for Armada 370 and Armada XP
*) It is integrated with the mvebu pinctrl driver so that GPIO pins
are properly muxed, and the GPIO driver knows which GPIO pins are
output-only or input-only.
*) Properly placed in drivers/gpio
*) More extensible mechanism to support platform differences. The
plat-orion driver uses a simple mask-offset DT property, which
works fine for Discovery MV78200 but not for Armada XP. The new
driver uses different compatible strings to identify the different
variants of the GPIO controllers.
