[PATCH 3/4] rombios interface for HVM S3
- add S3 package in ACPI DSDT table. Guest OS will get S3 value from
this package and write the value to PM1A control register to
trigger S3 suspend.
- Add S3 resume logic in rombios post code. the CMOS shutdown
register is used to indicate if this is a S3 resume.
- if it is s3 resume, rombios will get wakeup vector from ACPI FACS
table and jump to wakeup vector. Per ACPI spec, the wakeup vector
jumping must be the forms CS:IP, in which CS=(wakeup vector>>4)
IP=(wakeup vector)&0xF, for example, for vector=0x12345,
CS:IP=0x1234:0x5
Note: clobber_entry_point will clobber the post entry, which make S3
resume not work. We will directly jmp to POST Entry if it in S3
Resume path.
