crypto: ccp: Add the SNP_SET_CONFIG command
The SEV-SNP firmware provides the SNP_CONFIG command used to set various
system-wide configuration values for SNP guests, such as the reported
TCB version used when signing guest attestation reports. Add an
interface to set this via userspace.
[ mdr: Squash in doc patch from Dionna, drop extended request/
certificate handling and simplify this to a simple wrapper around
SNP_CONFIG fw cmd. ]
