regulator: act8865: Fix act8600_sudcdc_voltage_ranges setting
[ Upstream commit f01a7beb6791f1c419424c1a6958b7d0a289c974 ]
The act8600_sudcdc_voltage_ranges setting does not match the datasheet.
The problems in below entry:
REGULATOR_LINEAR_RANGE(19000000, 191, 255, 400000),
1. The off-by-one min_sel causes wrong volatage calculation.
The min_sel should be 192.
2. According to the datasheet[1] Table 7. (on page 43):
The selector 248 (0b11111000) ~ 255 (0b11111111) are 41.400V.
Also fix off-by-one for ACT8600_SUDCDC_VOLTAGE_NUM.
