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. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 44565
