power: bq2419x: Not use charging termination
Tegratab system can draw over charger power (5V*2A), unexpect
charging termination happen under 99% SOC.(around 93%~98%).
BQ charger occur charging termination when Vbatt is above
recharge threshold voltage(4208mA - 100mV = 4108mA) and
current is below ITERM(256mA).
So we need to disable charging termination and control charger
enable/disable with check SOC.
When SOC over 100%, disable charging and under 99% SOC, enable charger.
