Subject: [PATCH 3/5] regulator: lp872x: initialize the DVS mode

 The platform specific configuration(general_config) is optional.
 However, the DVS settings should be configured explicitly while
 loading the driver.
 This patch enables configuring the default DVS mode even though
 the platform data is not defined.
