regulator: s2mpa01: Use correct register for buck1 ramp delay
Fix the register for ramp delay of buck1 regulator. Buck1 and buck6 share the field (offset 4) in ramp delay register S2MPA01_REG_RAMP2. The driver used the same register and field for ramp delay of buck3 and buck1. This lead to updating of ramp delay of buck3 when setting buck1 and actually the ramp delay of buck1 was never set.
