Haiwei Li 374ad1c9ed dm: pm: add s3 support for an ovmf-booted User VM ...

For ovmf-booted User VM, we should set CMOS shutdown status register
(index 0xF) as S3_resume(0xFE). So ovmf will read it and start S3 resume
at POST entry.

And ovmf will read waking vector from FACS table and transfer control to
guest.
