sev/i386: add command to initialize the memory encryption context

Browse source 
When memory encryption is enabled, KVM_SEV_INIT command is used to
initialize the platform. The command loads the SEV related persistent
data from non-volatile storage and initializes the platform context.
This command should be first issued before invoking any other guest
commands provided by the SEV firmware.
