[PATCH v1 1/4] arm64: dts: ti: var-som-am62p: fix Ethernet PHY configuration

[Stefano Radaelli]

Fix the Ethernet device tree description on the VAR-SOM-AM62P.

Enable the CPSW Ethernet controller and correct the Ethernet PHY
description by modelling the PHY power supply and adding the required
board-specific PHY properties.
