meta-ibm: sbp1: phosphor-virtual-sensor: Calculate input current for IR3826x

The IR38263/IR38060 cannot measure the input current or input power,
thus calculate it from the output power, output current and input
voltage using predefined power offset and internal resistance.

Tested: Confirmed that new sensors appear in webui and provide sane
        sensor readings.
