intel/i945: Use romstage_handoff for S3

Don't use scratchpad registers when we have romstage_handoff
to pass S3 resume flag. Scratchpad register was read too
late in ramstage so acpi_is_wakeup_s3() did not evaluate
correctly.

This fixes low memory corruption at 0x1000-0x102c and the lack
of coreboot tables (util/cbmem not working) after S3 resume.

This also fixes console log from reporting early in ramstage
"Normal boot" while on "S3 resume" path.
