mb/prodrive/hermes: Add VBT for Avalanche systems

The Hermes mainboard is used in different system configurations. The
current VBT for Poseidon systems is unsuitable for Avalanche systems
because display ports are connected differently.

Add a new field in the BMC config EEPROM layout and use it to choose
the correct VBT for every system configuration.
