regulator: tps6586x: Fix list minimal voltage setting for LDO0
According to the datasheet, LDO0 has minimal voltage 1.2V rather than 1.25V. Table 3-39. VLDO0[2:0] Settings VLDOx[2:0] VOUT (V) VLDOx[2:0] VOUT (V) 000 1.20 100 2.70 001 1.50 101 2.85 010 1.80 110 3.10 011 2.50 111 3.30 Signed-off-by: Axel Lin <axel.lin@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
