[PATCH v6 1/7] power: act8945a_charger: Remove "battery_temperature"

From: Wenyou Yang
Date: Thu Aug 18 2016 - 21:28:35 EST


Remove "battery_temperature" member, it is redundant, it is the
hardware's responsibility to handle TH pin properly.
It is unnecessary to use the dt property to check if there is
a battery temperature monitor or not.
