haswell: use s3_resume field in romstage_handoff
Now that there is a way to disseminate the presence of s3 wake more
formally use that instead of hard coded pointers in memory and stashing
magic values in device registers. The northbridge code picks up the
field's presence in the romstage_handoff structure and sets up the
acpi_slp_type variable accordingly.
