4.14-stable review patch. If anyone has any objections, please let me know.

commit 406d2b6ae3420f5bb2b3db6986dc6f0b6dbb637b upstream.
In a subsequent patch we will enable building security.c for Book3E. However the NXP platforms are not vulnerable to Meltdown, so make the Meltdown vulnerability reporting PPC_BOOK3S_64 specific.
