soc/amd/picasso: Generate ACPI pstate and cstate objects in cb
Add code to generate p-state and c-state SSDT objects to coreboot.
Publish objects generated in native coreboot, rather than the ones
created by FSP binary.
BUG=b:155307433
TEST=Boot morphius to shell and extract and compare objects created in
coreboot with tables generated by FSP. Confirm they are equivalent.
BRANCH=Zork
