x86/microcode/AMD: Concentrate patch verification

Browse source

Add a verify_patch() function which tries to sanity-check many aspects
of a microcode patch supplied by an outside container before attempting
a load.

Prepend all sub-functions' names which verify an aspect of a microcode
patch with "__".

Call it in verify_and_add_patch() *before* looking at the microcode
header.
