The reason we add *pdev in struct aat2870_regulator is to use it
to get a pointer to struct aat2870_data.
Save a pointer to struct aat2870_data instead of pdev in struct
aat2870_regulator, this change makes the intention more clear.

Current code has off-by-one n_voltage settings for AUTO/DOWN*/LDO* regulators.
Take ldo1 as example:
n_voltage should be (3.6 - 0.9) / 0.1 + 1 = 28
Table 76. LDO1OUT - LDO1 output voltage select register (address 2Dh) bit description[1]
Bit Symbol Access Description
4:0 ldo1_out R/W VO(prog) = 0.9 + ldo1_out × 0.1 V (max 3.6V); e.g.
00000 : 0.9 V
00001 : 1.0 V
11000 : 3.3 V
11011 : 3.6 V
11111 : 3.6 V
The n_voltage settings for HCLDO and MEMLDO are also wrong.
n_voltage for HCLDO and MEMLDO should be (3.6 - 0.9) / 0.1 + 1 = 28
Table 88. HCLDOOUT - HCLDO output voltage select register (addr. 39h) bit description[1]
Bit Symbol Access Description
4:0 hcldo_out R/W VO(prog) = 0.9 + hcldo_out × 0.1 V (max 3.6 V); e.g.

11011 : 3.6 V

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]).
