11.- finalPstateChange() from init_fidvid_Stage2 (BKDG says just "may", anyway)
12.- generate ACPI for p-states. FIXME
Needs more assessment. There's some kind of fixed support that
does not seem to depend on CPU revision or actual MSRC001_00[68:64]
as BKDG apparently requires.

At least for Tilapia board:
src/mainboard/<vendor>/<model>/acpi_tables.c write_acpi_tables(...) calls
acpi_add_ssdt_pstates(...)
in /src/northbridge/amd/amdfam10/amdfam10_acpi.c
which apparently copies them from static info in
src/mainboard/<vendor>/<model>/acpi/cpstate.asl
12.- generate ACPI for p-states.
generated in powernow_acpi.c pstates_algorithm()
"must also be completed"
