Reserve a small persistent SMRAM subregion for OPAL S3 unlock state, so the payload-provided OPAL secret can survive SMM handler reload on S3 resume. Expose the region base/size to SMM via smm_runtime and provide an accessor for SMM code. Clear the region on cold boot/reboot, but preserve it when waking from S3.
