When I've considered implementing this in the past I've thought about
doing something like having DAI groups which own the physical link
configuration when you've got more than one logical link on the same
physical infrastructure.  The physical configuration would then get
punted up to the group level and we'd need some mechanism for the group
to start clocks when required.

I've only ever thought about it though so there may be some problems
there I've not come up with yet.  Might be useful to start the
refactoring for the clocks anyway, might be useful for the
reconfigurable channel allocation cases too.
