power: qpnp-bms: increase the high soc adjust threshold to 98

Previously, the BMS driver does not allow OCV corrections when SoC
is above 90. This is because the BMS driver could accidentally pull
down a faked high OCV at end of charge and cause a bad user experience.
However, now that a check was added to make sure estimated SoC is below
15%, we do not need this check any more, since if estimated SoC is below
15%, we always want to correct anyways.

Raise the threshold from 90 to 98 to fix this issue and always correct
when SoC is below 98 and soc_est is below 15.
