These are the devices documented by the Rainier device tree. With this
we can see the guest discovering the multiplexers and probing the eeprom
devices:
i2c i2c-2: Added multiplexed i2c bus 16
i2c i2c-2: Added multiplexed i2c bus 17
i2c i2c-2: Added multiplexed i2c bus 18
i2c i2c-2: Added multiplexed i2c bus 19
