[PATCH v2 0/2] Add NETC support for i.MX95

[Wei Fang]

We have added support for i.MX95 NETC related drivers, so it's time to
add NETC related nodes in DTS and enable the use of ENETC 0.

[PATCH v2 2/2] arm64: dts: imx95-19x19-evk: add ENETC 0 support

[Wei Fang]

Add ENETC 0 (1G ethernet port) support for i.MX95-19x19-EVK board. In
addition, because all ENETC instances share MDIO bus, so enable EMDIO
at the same time.
