Ampton: correct thermistor reading function
The charger thermistor on ampton is tied to the PP3300_A rail, rather
than the PP6000_LDO_OUT rail which bip used. As such, the charger
reading does not depend on AC being present, but does depend on the A
rail being enabled.
BUG=None
BRANCH=octopus
TEST=loaded onto apel and confirmed "ectool temps all" now returns
charger temperature with AC unplugged, in G3 "temps" will show the
ambient and charger sensors as not powered
