Fix AXI4 RegisterRouter on Wire Clone

+ replace `m _` with `() => m` in the method without a parameter list
  and by-name params;

Methods without a parameter list and by-name params can no longer be converted to functions as `m _`, write a function literal `() => m` instead

+ Use chisel3.experimental.SourceInfo;

In legacy code it is ok to clone a Wire using Wire()
now the requirement is more strict and WireDefault is needed
