mb/prodrive/hermes: Configure ALC888 port B Vref
Define a new field in the board config EEPROM layout for port B Vref.
Write port B Vref settings to unused non-volatile NID 0x12 instead of
NID 0x18, the actual port B NID. Because per-port Vref settings don't
persist after codec resets, a custom Realtek driver (ab)uses NID 0x12
to restore port B Vref after resetting the codec.
