WRT3200ACM: reverted to network switch, instead of DSA

WRT3200ACM has switched to DSA, loosing the ability to configure
the network switch from LiCI or use port mirroring. The physical ports
are exposed as VLANs: lan1, lan2, lan3, lan4, and wan. Custom VLANs
can be created, in an obfuscated way lan1.1, lan1.2, etc.

This patch reverts the changes mentioned above. Two physical interfaces
are exposed: lan, and wan with separate MAC addresses. The ability to
create custom VLANs, and mirror ports in LuCI is restored.
