Jonas Gorski eea227c60d brcm63xx: probe gpio controllers through DT
Add a generic mmio gpio controller based driver and probe it
through device tree.

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.
