pc: simplify MachineClass::get_hotplug_handler handling

By default MachineClass::get_hotplug_handler is NULL and concrete board
should set it to it's own handler.
Considering there isn't any default handler, drop saving empty
MachineClass::get_hotplug_handler in child class and make PC code
consistent with spapr/s390x boards.

We can bring this back when actual usecase surfaces and do it
consistently across boards that use get_hotplug_handler().
