What possible build coverage are we talking about when building highbank
on x86, for example? And what does a build failure in that configuration
tell you if it builds and boots fine on your hardware?

So make highbank depend only on the arches for which it is supposed to
work but not for *all* arches. Look at how the other edac drivers do it,
x86 ones depend on X86, tile on tile, etc, etc. Why should highbank be
special?

Simple: drivers should be selectable/buildable only on the arches
they're supposed to run on.
