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 Change-Id: I2ae03899fba8a436e34452bbc644f5e872afd408 Signed-off-by: Diana Z <dzigterman@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/1457076 Reviewed-by: Furquan Shaikh <furquan@chromium.org> Reviewed-by: Jett Rink <jettrink@chromium.org>
