soc/amd/picasso: Create picasso as a copy of stoneyridge
So that everyone can see what's being updated from stoney, we're starting with a direct copy of the stoney directory. There are arguments both for and against doing it this way, but I believe This the most transparent way. We've moved much of the duplicated stoney code into the soc/amd/common directory and will continue that work as it becomes obvious that we have unchanged code between the SOCs. Makefile.inc has been renamed as makefile.inc so that it won't build in jenkins until the directory is updated. Other than that change, this is an exact copy of the stoneyridge SOC directory which will be updated in the follow-on commits in the patch train.
