2022-08-12soc/amd/cezanne,common: factor out CPPC code to common AMD SoC codeFelix Held
The Cezanne CPPC ACPI table generation code also applies to Sabrina, so move it to the common AMD SoC code directory so that it can be used for Sabrina too.

2022-01-26soc/amd/cezanne,picasso,sabrina: factor out get_threads_per_coreFelix Held
This code is common to at least all Zen-based APUs (Picasso, Cezanne, Sabrina) and is also useful outside of the SoC-specific dynamic ACPI table generation code.

2021-10-19acpi/acpigen: Constify CST functions' pointersAngel Pons
The `acpigen_write_CST_package` and `acpigen_write_CST_package_entry` functions don't modify the provided C-state information. So, make the pointer parameters read-only to enforce this. Also constify arguments where possible.
