mb/amd/mandolin: Add Picasso CRB
Mandolin is the CRB for AMD Picasso and Dali. The mainboard code still needs a little cleanup and verification, but I'll do that in a follow-up to have a non Chromebook board using the Picasso SoC code in tree as soon as possible to be able to detect some possible breakage.
