Use a fallback compatible since for especially for generic
defensive setup of parameters, both 6030 and 6032 are the same and
U-Boot actually uses a generic 6030/32 function to enable the
charger.

+
+description: |
+  The battery charger needs to be configured to do any charging besides of
+  precharging. The GPADC in the PMIC has to be used to get the related
