ARM: dts: ixp4xx: Fix up Actiontec MI424WR DTS files

The KS8995 switch was unconditionally wired to EthC (eth1)
on both MI424WR variants, this is wrong: the D revision has
the switch connected to EthB (eth0) so pull this assingment
out of the generic MI424WR DTSI file and make it a property
of the respective variants instead.
