Subject[PATCH] regulator: Remove MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros
From

In current implementation, the original macro implementation assumes the caller
pass the parameter starting from 1 (to match the register names in datasheet).
Thus we have unneeded plus one then minus one operations
when using MAX8997_REG_BUCK1DVS/MAX8997_REG_BUCK2DVS/MAX8997_REG_BUCK5DVS macros.

This patch removes these macros to avoid unneeded plus one then minus one operations
without reducing readability.
