ARM: dts: vf610: Add device trees for dual Ethernet board

Add a device trees for the dual Ethernet Colibri Carrier Board.
The Carrier Board has a second Ethernet PHY on board and connects
it to the second Ethernet Controller of Vybrid. Therefor the
Carrier Board is only usable with Vybrid based modules (Colibri
VF50/VF61). Furthermore, the Carrier Board has two additional
UARTs beside the three default Colibri UARTs.

The schemata of the Ethernet part of a dual Ethernet Carrier
Board for Vybrid can be found online at:
