commit a9d0adc upstream. Refactor struct cpuinfo_x86 so that the vendor, family, and model fields are overlaid in a union with a 32-bit field that combines all three (together with a one byte reserved field in the upper byte). This will make it easy, cheap, and reliable to check all three values at once. See https://lore.kernel.org/r/Zgr6kT8oULbnmEXx@agluck-desk3 for why the ordering is (low-to-high bits): (vendor, family, model) [ bp: Move comments over the line, add the backstory about the particular order of the fields. ] Intel-SIG: commit a9d0adc x86/cpu/vfm: Add/initialize x86_vfm field to struct cpuinfo_x86.

Add SST support for ClearWater Forest
Note: this PR also includes all the patches in #60, because it depends on the CWF CPUID support in that PR.
Tests:
Tested on CWF, SST driver can be loaded, and SST information can be dumped via intel-speed-select userspace tool.
