Revert to the original explicit approach and document the reasoning
behind it.

v2:
  * DG2 needs to be covered too. (Matt)

v3:
  * Full version check for Gen12 to avoid catching all future platforms.
    (Matt)

v4:
  * Be totally explicit on the Gen12 branch. (Andrzej)

for v4 as well.

Thanks, pushed!

So next I have that patch which moves the register/bits selection logic to engine init time. I will send it out rebased but do not intend to merge before the tlb invalidation selftest can land upstream.
