[RETEST] mb/prodrive/hermes: Number Ethernet devices

The Prodrive Hermes mainboard has four i211 Ethernet NICs and an i210
Ethernet NIC, but their numbering isn't consistent with the PCIe root
port function numbers. Without any device in the PEG slot, Linux uses
the following names:

PHY 0 ---> [RETEST]
 PHY 1 ---> enp4s0
 PHY 2 ---> enp3s0
 PHY 3 ---> enp1s0
 PHY 4 ---> enp2s0

These names would probably change if the PEG slot is populated, as the
secondary bus numbers would get shifted.

To avoid this, describe the NICs using SMBIOS Type41 entries with the
correct instance numbers. With this patch, Linux uses these names:

[RETEST]

PHY 0 ---> eno0
 PHY 1 ---> eno1
 PHY 2 ---> eno2
 PHY 3 ---> eno3
 PHY 4 ---> eno4
