soc/amd/common: factor out SMU code from Picasso
The SMU mailbox access code from Picasso can be reused in the next
generation, so factor out the code to soc/amd/common/block/smu. Since
the mailbox register offsets in the indirect address space, the number
of arguments and the message IDs don't always match between different
devices, keep those in the soc-specific directories.
