spherion: support thermal charge policy
supports skin temperature thermal policy from charge current
setting via charger temperature threshols hit/release.
setting input max current to 3.1A.
The charging limitation is listed below:
While NB in OS, sample temperature as chager task
Tsens < 48 degree C , No limitation
Tesen > 48 degree C , Limit charge current at 3.1A
Tsens > 52 degree C , Limit charge current at 2.2A
BUG=b:183174897
BRANCH=asurada
TEST=The thermal test report PASS, make builadall PASS.
