spapr: Add DRC release method

At the moment, spapr_drc_release() has an ugly switch on the DRC type to
call the right, device-specific release function.  This cleans it up by
doing that via a proper QOM method.

It's still arguably an abstraction violation for the DRC code to call into
the specific device code, but one mess at a time.
