PS19: 
I think it would have been better to simply enable everything. The
current situation where we enable random things by default leads
to incomplete board ports. Looking at the code for boards already
in the tree, we can neither tell what bits they need to be set nor
what bits would conflict if we'd set them all.

Which led to the bad situation, I guess, that somebody needs an
additional bit set but doesn't know if it's safe to do so for all
boards.

It seems too late to fix for older platforms without looking into
a lot of boards or risking regressions. But maybe it's not too
late for Tiger Lake?
