soc/amd/cezanne: select soc-specific ACPI functionality
This doesn't select HAVE_ACPI_TABLES, so no ACPI tables will be
generated for now. There's also no globalnvs.asl that corresponds to
nvs.h yet. The added nvs.h has some currently unused fields, but still
having them in the struct aligns it with Picasso and also might reduce
the noise in future ACPI patches a bit. When most of the ACPI code for
Cezanne has landed, we need to do a cleanup though.
