x86: Minimise printk spew from per-vendor init code

In the default case where the kernel supports all CPU vendors,
we currently print out a bunch of not useful messages on every
system.

32-bit:
KERNEL supported cpus:
  Intel GenuineIntel
  AMD AuthenticAMD
  NSC Geode by NSC
  Cyrix CyrixInstead
  Centaur CentaurHauls
  Transmeta GenuineTMx86
  Transmeta TransmetaCPU
  UMC UMC UMC UMC

64-bit:
KERNEL supported cpus:
  Intel GenuineIntel
  AMD AuthenticAMD
  Centaur CentaurHauls

Given that "what CPUs does the kernel support" isn't useful for
the "support everything" case, we can suppress these printk's.
