[coreboot] Dont filter supported CPUs on a mainboard by the CPUID

[i1w5d7gf38keg at tutanota.com]

What is the benefit of such a list? I cant see any benefit. Its only additional work that is useless.

A example for CPUID-List blocking functionality is commit I63d308477a22a9e55ceed1b6b36e63a3044c2354
