Gregory CLEMENT 5715092a45 pinctrl: armada-37xx: Add gpio support 
GPIO management is pretty simple and is part of the same IP than the pin
controller for the Armada 37xx SoCs.  This patch adds the GPIO support to
the pinctrl-armada-37xx.c file, it also allows sharing common functions
between the gpiolib and the pinctrl drivers.

Gregory CLEMENT 87466ccd94 pinctrl: armada-37xx: Add pin controller support for Armada 37xx 
The Armada 37xx SoC come with 2 pin controllers: one on the south
bridge (managing 28 pins) and one on the north bridge (managing 36 pins).

At the hardware level the controller configure the pins by group and not
pin by pin. This constraint is reflected in the design of the driver:
only the group related functions are implemented.
