Log:
  powerpc/SMP: Don't spam the console with AP bringup messages
  
  Especially on new POWER9 systems, the console can be filled with
  
    SMP: AP CPU #XX launched
  
  messages.  This can also slow down the console printing.  Instead, do what
  x86 now does, as of r333335, and print it all on one line, unless
  bootverbose is set.
