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.
