regulator: max8925: fix enabled/disabled judgement mistake
Max8925 ldo status should be determined by two factors:
1. power up/down sequence selection(LDOCTL[4:2]).
2. i2c enable bit(LDOCTL[0]).
Max8925 ldo support two types of power up/down sequence:
1. flexible sequence(LDOCTL[4:2] = 0~6).
2. i2c sequence(LDOCTL[4:2] = 7).
With flexible sequence selected, the ldo is enabled during power up by default.
With i2c sequence selected, the ldo is controlled by the i2c enable bit(LDOCTL[0]).
