Daniel González Cabanelas e55b4b436e 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.
