[X86] Minimise printk spew from per-vendor init code.

[Dave Jones <davej@redhat.com>]

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

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

64bit:
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.
