Caveh Jalali 0f9a4fba96 charger: set PPVAR_SYS to normal battery voltage
the isl9238 needs to see a higher PPVAR_SYS voltage than we were using
to avoid tripping Low_VSYS.  Low_VSYS is one of the terms causing the
isl9238 to assert PROCHOT.  its lowest default voltage threshold is
about 6.1v which is too close to the battery "minimum" that we were
using to set PPVAR_SYS.  it's better to use the "normal" battery
voltage so the running-on-AC case is similar to the running-on-battery
case.

BUG=b:78911901
BRANCH=none
TEST=examined isl9238 regs to verify it is no longer tripping Low_VSYS
