On board rev A, the network interface labels for the switch ports
written on the front panel are different than on rev B and later.

This patch fixes network interface names for the switch ports according
to labels that are written on the front panel of the board rev B.
They start from ETH3 and end at ETH10.

This patch also introduces a separate device tree for rev A.
The main device tree is supposed to cover rev B and later.

I applied this but it generated errors, you should have got some reports
from the kernel build robot.

cheers
