[PATCH v4 net-next 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.

Changes in v4:
- Retargeted to net-next.
- Fixed the port labels (ETH5 was ETH4, ETH7 was ETH6, ETH9 was ETH8,
  ETH11 was ETH10).

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.
