I'm fine with doing it with tables (though just having two static CODEC
driver structures would be a bit cleaner).  The pattern with probe() is
usually that there's some base set of controls all the devices have
which then gets device specific controls/routes/whatever added to it so
you get benefits fromm sharing the table but in this case the table is
so tiny anyway that I'm not sure it's worth caring.
