xen: register legacy backends via xen_backend_init
It is okay to register legacy backends in the middle of xen_bus_init().
All that the registration does is record the existence of the backend
in xenstore.
This makes it possible to remove them from the build without introducing
undefined symbols in xen_be_init(). It also removes the need for the
backend_register callback, whose only purpose is to avoid registering
nonfunctional backends.
