This seems to make TDM configuration mandatory which seems like a step
back - if it's been set up then of course we need to use it but if it's
not been configured we should be able to just infer something from
hw_params as we have been doing.  Checking to see if the relevant values
have been set and falling back to using hw_params seems better.

Otherwise this looks good.
