power: bq2419x: Not use charging termination
BQ2419x charger generate charging termination automatically when
Vbatt is under recharge threshold voltage(4208mA - 100mV = 4108mA) and
charging current is below ITERM(256mA).
For this reason, when Tegratab system spend more than charger power(5V*2A),
unexpect charging termination occur under 99% SOC.(around 93%~98%).
So we need to disable charging termination fuction and control charger manually.
Disable charging when SOC over 100%(set by chg_complete_soc) and
Batt voltage is over 4202mV and cahrging cuurent is under 256mA(over -256mA),
besides restart charging when SOC is under 99% or Batt voltage is under 4140V,
for prevent unexpected charging done.
