ar71xx: connect GMAC0 to the internal switch on DB120
Because the external switch has no driver yet, connect GMAC0 to the PHY4 of the internal switch for now. This allows to use the DB120 board as a router with 4LAN+1WAN ports. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@29557 3c298f89-4303-0410-b956-a3cf2f4a3e73
