PSUSensor: Add Offset attribute

The value of "Offset" is measured by power team and is considered as the
correctest calibration value for making the sensor reading value much
more precise on the platform.

Add the customizable attribute "Offset" to be able to adjust the raw
data and than update to the "Value" property on dbus.

Tested: Add the following configuration to entity-manager
        {
            "Address": "0x68",
            "Bus": "32",
            "Labels": [
                "vout1",
                "iout1",
                "pout1",
                "temp1"
            ],
            "Name": "onboard_p12v",
            "Thresholds": [
                ...
            ],
            "Type": "RAA228000",
            "iout1_Max": 108.0,
            "iout1_Offset": -0.25,
            "pout1_Max": 900.0,
            "pout1_Offset": -5.0,
            "vout1_Max": 13.0
        },
    - Check the reading value on dbus of this sensor is equal to the
      value we expected.
