This is part of the reason why the driver_data field is present in the
constraints - the driver can take that and use it as a pdata within
pdata structure.  It's not terribly nice to do that but it's possible.
A standard parameter might cause too much complexity as drivers try to
implement it even if they don't really need to (for example, due to
having soft control of this stuff already).
