bcm63xx: kernel: fix up bcm63268 roboswitch gpio registers Some BCM63268 bootloaders may leave gpio registers, related to the roboswitch, disabled before loading the OpenWrt firmware. As result of this the switch won't work. These registers, if not enabled, probably avoid forwarding packets. Signed-off-by: Daniel González Cabanelas <dgcbueu@gmail.com>
