Add a configuration option to enable or disable the reverse boost fix for the DC charging path. Some board designs do not utilize the DC_IN path on the PMIC, however they do use the presence detection of DC_IN to enable the auto switching and interrupt features. In these particular configurations the PMIC does not control the DC OVP FETs. Hence add an option to enable or disable the DC path workaround and leave the workaround disabled by default.
