osiris: Discharge on AC when high MLCC noise
Charger will work on the hybrid mode if battery full and system
current over 3A. The voltage gap between the Vsys and Vbat will
cause the Vsys has high ripple, Although it is normal design
behaviors, But it will cause MLCC noise a bit larger than other
conditions.
This CL force battery discharge when battery full, So the battery
MOS of NVDC charger will turn on always, it make the Vsys same
as Vbat and the noise has been improved.
BUG=b:246214501
TEST=check battery discharging when battery full
BRANCH=none
