Sidecar fan current scaling incorrect #2202

Not sure if this is a hubris or humility issue, but the ADM1272 current measurements on the fans for Sidecar have the incorrect scaling. They are reporting a current that is 2x the actual current.

From humility sensors:

NAME                 KIND                  VALUE UNPWR   ERR MSSNG UNAVL TMOUT
V54_FAN1             current                5.97     0     0     0     0     0

Actual current is 3.0A on an external electronic load. The current sense resistor on the fan HSCs is 2 milliohms but the main HSC is 1 milliohm.
