Change subject: [WIP] soc/amd/common: factor out SMU code from Picasso
......................................................................

Patch Set 2:

Is it valuable to further separate common/block/smu support into the supported generations then have soc/<name> select the right one?  (Not that I'm anticipating being able to open source much SMU code soon, but would like to plan for it.)
