Pull x86 SEV updates from Borislav Petkov:

 - Make the SEV internal header really internal and carve out the
   SVSM-specific code into a separate compilation unit, along with other
   cleanups and fixups

[ TLA translation service: 'SEV' is AMD's 'Secure Encrypted
  Virtualization' and SVSM is an ETLA ('Enhanced TLA') for 'Secure
  VM Service Module'.

  Some of us have trouble keeping track of this all and need all the
  help we can get ]
