Remove old code that will be replaced by rewritten and shorter functions in
the next patch.  Keep struct ibmebus_dev and struct ibmebus_driver for now,
but replace ibmebus_{,un}register_driver() by dummy functions.  This way, the
kernel will still compile and run during the transition and git bisect will
be happy.
