The i.MX95 ENETC has been upgraded to revision 4.1, which is different from the LS1028A ENETC (revision 1.0) except for the SI part. Therefore, the fsl-enetc driver is incompatible with i.MX95 ENETC PF. So add new nxp-enetc4 driver to support i.MX95 ENETC PF, and this driver will be used to support the ENETC PF with major revision 4 for other SoCs in the future. Currently, the nxp-enetc4 driver only supports basic transmission feature for i.MX95 ENETC PF, the more basic and advanced features will be added in the subsequent patches. In addition, PCS support has not been added yet, so 10G ENETC (ENETC instance 2) is not supported now.
