regulator: bd7181x: skip DVS buck setup if it's not enabled 

The DVS buck setup should only be done in case that i2c_dvs_enable is
true.  Otherwise, we should skip it to avoid the following noisy
messages.

  bd7181x-pmic bd7181x-pmic: Buck0: DVS High-Low[0 - 0].
  bd7181x-pmic bd7181x-pmic: bd7181x_buck12_dvs_init(): not found selector for voltage [0]
  bd7181x-pmic bd7181x-pmic: bd7181x_buck12_dvs_init(): not found selector for voltage [0]
