[PATCH v3 5/5] arm64: dts: ti: iot2050: Add icssg-prueth nodes for PG2 devices

From: Jan Kiszka
Date: Fri Nov 03 2023 - 14:32:46 EST

From: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>

Add the required nodes to enable ICSSG SR2.0 based prueth networking.

As the driver still needs to be extended for SR1.0 support, keep related
nodes disabled on PG1 devices.

Signed-off-by: Jan Kiszka <jan.kiszka@xxxxxxxxxxx>
