[PATCH 1/2] arm64: dts: imx94: add basic NETC related nodes

[Wei Fang]

The NETC related nodes for i.MX94, this NETC has two PCIe buses, the bus
0 has 1 ENETC instance, one PTP timer, one RCEC and a switch, currently,
the switch is not added due to the DT binding and the driver is not
ready at the moment. The bus 1 has three ENETC instances, 2 PTP timers,
1 RCEC and one EMDIO.
