mvebu: clearfog: assign SFP port to WAN zone

The single SFP port is meant for direct media access to WAN, such as
VDSL2, GPON). While it could also be used for in-home fiber, it is much
more likely that the LAN is standard ethernet, especially considering
that SFP is the onmly port that can go beyond 1Gbps.
