Jonas Gorski 343ec8d645 brcm63xx: use consistent gpio chip labeling for OF/non-OF
Ensure gpio chips are always labeled the same; this allows simplifying
any arch setup gpio lookups.

Jonas Gorski ca7f6d28c8 brcm63xx: Add DGND3700 v1 / DGND3800B support
This adds support for the Netgear DGND3700 v1 and DGND3800B.

DGND3700 v1 and DGND3800B are exactly the same router, only one difference,
the factory firmware. This patch produces two factory firmwares for each router.

The router includes an onboard NAND flash for extra storage. NAND is currently
not supported in bcm63xx, so no code added for this part. The NOR flash (32MB)
is enough for storing an openwrt firmware.

Jonas Gorski eed031d460 brcm63xx: brcm63xxpart: fix buffer overrun in of parser
We never account for the added partitions from the tag parser, so
allocated two partioness less than needed. This can cause issues when
the memory gets reused before the mtd code can actually add the
partitions.

Fixes oopses like:

Add a generic mmio gpio controller based driver and probe it

Use aliases for base calculation until we converted all users to
device tree or named gpios.

Convert bcm63xx_enet's ephy-reset gpio to use a named gpio.

While at it, remove the duplicate reset gpio defintion for livebox.
