We have HW_COMPAT_*, however that's only bound to machines, not other
things (like accelerators). Behind it, it was register_compat_prop()
that played the trick. Let's export the function for further use
outside HW_COMPAT_* magic.
Meanwhile, move it to qdev-properties.c where seems more proper (since
it'll be used not only in machine codes).
