nit: |shell_port|. Also, is the next line still true?

Not for this CL: It would be nice if this parameter was always required.

Once ash is the default and the classic code isn't needed it can be removed. I
nuked the comment.
Indeed.

   // TODO(sky): temporary, will eventually go away.
-  WmShell* wm_shell = nullptr;
+  ShellPort* shell_port = nullptr;
   // Shell takes ownership of |primary_window_tree_host|. This is only used
   // by mash.
   aura::WindowTreeHostMus* primary_window_tree_host = nullptr;
