crypto: ccp - Cache SEV platform status and platform state

Browse source

Cache the SEV platform status into sev_device structure and use this
cached SEV platform status for api_major/minor/build.

The platform state is unique between SEV and SNP and hence needs to be
tracked independently.

Remove the state field from sev_device structure and instead track SEV
state from the cached SEV platform status.
