In the past we used this configuration for SOF CI tests with the
MinnowBoard + an RT5682 eval board. We gradually fried most boards and
no longer check this capability for each SOF PR.

So I would agree we can avoid changing anything for BYT/CHT and possibly
APL, it'd be an untested configuration.

in other words, let's add this compatible/alt_id for platforms where we
know it'll be used.
