crypto: ccp: Add the SNP_COMMIT command
The SNP_COMMIT command is used to commit the currently installed version
of the SEV firmware. Once committed, the firmware cannot be replaced
with a previous firmware version (cannot be rolled back). This command
will also update the reported TCB to match that of the currently
installed firmware.
[ mdr: Note the reported TCB update in the documentation/commit. ]
