Well, the DAPM map needs to be global in some sense since it needs to
flow between CODECs and we need board widgets which are definitely not
fixed on an individual chip.  

I think I'd like a firm idea of how the cross device DAPM works before
we do anything with the prefixes since there's some overlap there (if
only due to the fact that half the controls come from DAPM), even if the
cross device DAPM doesn't actually work yet.  I think your current code
is probably going to work well with DAPM but I need to have a bit of a
think about that over the weekend.
