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.
