arch/x86: Fix S3 resume without stage cache
It was possible to have NO_STAGE_CACHE=n and at the same time have
TSEG_STAGE_CACHE=n and CBMEM_STAGE_CACHE=n. This resulted with a
failing attempt to load STAGE_POSTCAR from the stage cache, but not
loading it from CBFS either.
Make it a three-way choice between different STAGE_CACHE options.
For AGESA disable CBMEM_STAGE_CACHE by default, as it is no longer
needed to have functional ACPI S3 resume and it is not allowed
se use keyword select for symbols inside choice blocks.
