vc/amd/fsp/cezanne,mendocino: add FSP CCX CPPC HOB GUID and struct
To generate a complete _CPC ACPI object, coreboot needs the minimal and nominal core speed values which are specific to the CPU and not only the CPU family. Since this is done by an undocumented mechanism, FSP has to do this and puts the information we need into a HOB. This adds the HOB GUID and the structure of the HOB data.
