power: supply: mm8013: fix "not charging" detection
The charge_behaviours property is meant as a control-knob that can be
changed by the user.
Page 23 of [0] which documents the flag CHG_INH as follows:
CHG_INH : Charge Inhibit When the current is more than or equal to charge
threshold current,
charge inhibit temperature (upper/lower limit) ：1
charge permission temperature or the current is
less than charge threshold current ：0
So this is pure read-only information which is better represented as
POWER_SUPPLY_STATUS_NOT_CHARGING.
