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
