beckham: Use charge_only_mode from PPWS29.131-27-1-27

* The common binary doesn't have support for Mods whereas this
  one does have dependencies on libmodmanager, so switch to device
  specific. Our blob will simply override the one in common vendor
  thus no need to decommonize it just so we can use our own.
