Kodama: SMP battery cannot be charged in over discharge state
SMP battery uses HW pre-charge circuit and pre-charge current is
limited to ~50mA. Once the charge current is lower than IEOC level
within CHG_TEDG_EOC, and TE is enabled, the charging power path
will be turned off.
Charger vendor advice that disable EOC and TE when battery stays over
discharge state, otherwise enable EOC and TE.
BUG=b:142630134
TEST=Verified on both SMP battery and Celxpert battery in over
discharge state, all passed.
