Subject: [PATCH v4 net-next 02/13] dt-bindings: net: add i.MX95 ENETC support

The ENETC of i.MX95 has been upgraded to revision 4.1, and the vendor
ID and device ID have also changed, so add the new compatible strings
for i.MX95 ENETC. In addition, i.MX95 supports configuration of RGMII
or RMII reference clock.

Signed-off-by: Wei Fang <wei.fang@....com>
---
v2: Remove "nxp,imx95-enetc" compatible string.
v3:
1. Add restriction to "clcoks" and "clock-names" properties and rename
the clock, also remove the items from these two properties.
2. Remove unnecessary items for "pci1131,e101" compatible string.
v4: Move clocks and clock-names to top level.
