intel/sandybridge: Use common ACPI S3 recovery
Fix regression, S3 resume not working on sandy/ivy after commit
9d6f365 ACPI S3: Remove HIGH_MEMORY_SAVE where possible
There is some 20ms delay with ACPI S3 wakeup time due to MTRR setup
being done after the backup copy. Moving to RELOCATABLE_RAMSTAGE fixes
this delay by removing need of this backup entirely.
