Warnings on Edison

[Simon Glass]

Hi Andy,

When I build edison on master I recently started seeing this warning:

+board/intel/edison/dsdt.asl.tmp    210:         Name (SSCN, Package ()
+Warning  4089 -                Object is not referenced ^

+Warning  4089 -                      Object is not referenced ^

Do you have any thoughts on how to fix it?
