ar71xx: make the SFP port usable on RB2011*S boards
The port 6 of the switch is connected to the SFP cage on the RB2011*S boards. Add a helper function to correctly initialize the switch configuration data on those boards to make the SFP port usable. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 36799
