[PATCH v5 net-next 09/13] net: enetc: add i.MX95 EMDIO support

The verdor ID and device ID of i.MX95 EMDIO are different from LS1028A
EMDIO, so add new vendor ID and device ID to pci_device_id table to
support i.MX95 EMDIO. And the i.MX95 EMDIO has two pins that need to be
controlled, namely MDC and MDIO.
