regulator: lm363x: Fix off-by-one n_voltages for lm3632 ldo_vpos/ldo_vneg
[ Upstream commit 1e2cc8c5e0745b545d4974788dc606d678b6e564 ]
According to the datasheet https://www.ti.com/lit/ds/symlink/lm3632a.pdf
Table 20. VPOS Bias Register Field Descriptions VPOS[5:0]
Sets the Positive Display Bias (LDO) Voltage (50 mV per step)
000000: 4 V
000001: 4.05 V
000010: 4.1 V
....................
011101: 5.45 V
011110: 5.5 V (Default)
011111: 5.55 V
....................
100111: 5.95 V
101000: 6 V
Note: Codes 101001 to 111111 map to 6 V
The LM3632_LDO_VSEL_MAX should be 0b101000 (0x28), so the maximum voltage
can match the datasheet.
