powerpc/64: Make meltdown reporting Book3S 64 specific
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.
