spapr: Abolish DRC get_fdt method 

The DRConnectorClass includes a get_fdt method.  However
  * There's only one implementation, and there's only likely to ever be one
  * Both callers are local to spapr_drc
  * Each caller only uses one half of the actual implementation

So abolish get_fdt() entirely, and just open-code what we need.
