In this way many repeated macros can be removed. Now these macros are repeated only if the the LDO/BUCK ctrl registers have non-linear positions. The good thing is these ctrl registers are mostly linear so they are not passed as parameters. This patch reduces the code size and also allow easy addition of more s2mpxxx PMIC drivers which differs a lot in minimum/step voltages.
