From: Gregory CLEMENT <gregory.clement@free-electrons.com>

Add the nodes for the two pin controller present in the Armada 37xx SoCs.

Initially the node was named gpio1 using the same name that for the
register range in the datasheet. However renaming it pinctr_nb (nb for
North Bridge) makes more sense.

Minor changes for U-Boot because of the slightly different dts version
done by Stefan Roese.

Start to populate the device tree of the Armada 37xx with the pincontrol
configuration used on the board providing a dts.

From: Gregory CLEMENT <gregory.clement@free-electrons.com>

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.

Ported to U-Boot based on the Linux version by Stefan Roese.

From: Gregory CLEMENT <gregory.clement@free-electrons.com>

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 gpio and the pinctrl drivers.

Ported to U-Boot based on the Linux version by Stefan Roese.

To enable support for the Armada 37xx pinctrl driver, we need to
change the Kconfig symbol for the Armada 7k/8k pinctrl driver and its
dependencies to distinguish between both platforms and drivers.
