qdev: remove direct calls to print/parse

There's no need to call into ->parse and ->print manually.  The
QOM legacy properties do that for us.

Furthermore, in some cases legacy and static properties have exactly
the same behavior, and we could drop the legacy properties right away.
Add an appropriate fallback to prepare for this.
