[PATCH v3 2/2] arm/arm64: dts: Add MV88E6393X to CN9130-CRB device tree

The CN9130-CRB boards have a MV88E6393X switch connected to eth0. Add
the necessary dts nodes and properties for this.

This is based on the Marvell SDK. I've re-ordered the port entries to
be in ascending order renamed the wan ports and connected the SFP+.

Change in v3:
- Add review from Russell
- Change port at 10 to port at a
- Add maximum-power-milliwatt property to SFP

Changes in v2:
- Remove unused port0
- Label all ports "pN"
- Add interrupt connections
- Add SFP
