[PATCH v3 devicetree 2/2] powerpc: dts: t1040rdb: add ports for Seville Ethernet switch

Define the network interface names for the switch ports and hook them up
to the 2 QSGMII PHYs that are onboard.

A conscious decision was taken to go along with the numbers that are
written on the front panel of the board and not with the hardware
numbers of the switch chip ports. The 2 numbering schemes are
shifted by 8.

Changes in v3:
Renamed interfaces from swpN to ETHN, as per Andrew Lunn's suggestion.

Changes in v2:
Use the existing way of accessing the mdio bus and not labels.
