power: regulator: tps65941: Fix voltage calculation for ldo
As per TRM[0] Section 8.7.1 "TPS6594-Q1 Registers", LDOx_Vout
bit 6-1, define the NVM voltage settings.
Along side table 8-4 of above TRM, shows voltage to value mapping.
Driver wrongly using bits 5-1 to calculate voltage, and to convert
voltage to value driver was using buck's calculation.
So fix those calculation.
