[PATCH net-next v2 2/5] net: enetc: Enable probing of version 4.4 devices

The ENETC v4.4 devices are present on S32N79 SoCs and feature only
Pseudo-MAC ENETC ports, whose PFs use either the 0xe101 or the 0xe110
PCI device ID, and the VFs answer to the usual device ID of 0xef00.

While the ENETC PF instances are usually designated by the 0xe101 ID,
in newer IP versions the 0xe110 ID was introduced to indicate the
power-on reset default NETC switch management interface. These IDs
do not indicate any functional difference between the designated
ENETC instances, and can be interchanged and re-assigned at boot time
(i.e. from firmware).
