Log:
  [PPC] Fix loader call to instantiate-rtas
  
  OpenFirmware (OF) method instantiate-rtas was being called with a wrong
  rtas-base-address argument. It must use the memory that is already being
  allocated to this end instead. This issue was causing QEMU netboot to hang
  when building the FDT from OF DT.
