Firstly, the log/real mapping was incorrect in one case. Secondly, PMBus specifies that output voltages should be in the linear16 encoding. However, the YH-5151E is non-compliant and uses linear11. YM-2151E isn't affected by this. Fix this by converting the values inside the read functions. linear16 gets the exponent from the VOUT_MODE command. The device doesn't support it, so I have to manually supply the value for it. Both supported devices have now been tested to report correct vout values.
