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.
