    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.
