[PATCH 21/40] ab8500-btemp: Defer btemp filtering while initialising

[Lee Jones]

From: Rupesh Kumar <rupesh.kumar at stericsson.com>

Due to btemp filtering enabled during init, temp values reported
to charge algorithm driver started from 0. As a result,charge
algorithm was going into wrong state and charging was stopped.
