x86/CPUID: CPUID parsing rework, p1

From: Borislav Petkov <[email protected]>

Hi all,

this is the beginning of a long conversion. The final goal is to have one global, read-only CPUID hierarchy representation in arch/x86/ to replace all the gazillion places where CPUID is read and thus slim a lot of code. And improve all that X86_FEATURE* diddling. We'll see...

Anyway, these are the first three patches slimming cpuinfo_x86 by 80 bytes per CPU, by making vendor ID and brand name global and __ro_after_init.

Comments, reviews, etc are welcome, as always.

Thx.
