This commit adds a passthrough for PMBUS_IC_DEVICE_ID to allow Renesas voltage regulators to return the integrated circuit device ID if they would like to. The behavior is very device specific, so it hasn't been added to the general PMBUS model. Additionally, if the device ID hasn't been set, then the voltage regulator will respond with the error byte value. The guest error message will change slightly for IC_DEVICE_ID with this commit.
