ACPI / sleep: Do not save NVS for new machines to accelerate S3
NVS region is saved and restored unconditionally for machines without nvs_nosave quirk during S3. Tested some new machines and the operation is not necessary. Saving NVS region also affects S2RAM speed. The time of NVS saving and restoring depends on the size of NVS region and it consumes 7~10ms normally. This patch is to make machines produced from 2012 to now not saving NVS region to accelerate S3. Signed-off-by: Lan Tianyu <> Signed-off-by: Rafael J. Wysocki <>
