[PATCH v2 6/7] ARM64: dts: meson-gxbb-vega-s95: add reset for the ethernet PHY

[Martin Blumenstingl <martin.blumenstingl@xxxxxxxxxxxxxx>]

This resets the ethernet PHY during boot to get the PHY into a "clean"
state. While here also specify the phy-handle of the ethmac node to
make the PHY configuration similar to the one we have on GXL devices.
