Subformat options are ignored when setting up hardware parameters and

With introduction of subformats, copying hardware parameters becomes
a non-trivial operation. Implement a helper function to make things
simple.

I don't think that this extension is mandatory. The whole patch can be skipped
if the driver installs the subformat runtime constraint.
