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.
