azalea/lotus: CHG_LIMIT_GET_LIMIT disables override

[DHowett]

This is a repeat of bug #6 for azalea and lotus

Querying the charge limit with host command CHARGE_LIMIT_CONTROL mode CHG_LIMIT_GET_LIMIT reloads the charge limit from bbram, which overwrites the CHG_LIMIT_OVERRIDE flag.

The override flag is cleared when we read into charging_maximum_level here:
