ACPI: PM: save NVS memory for Lenovo G40-45

[ Upstream commit 88f6fcc95efa31683def52521ca353ae5a925905 ]

[80a5e32a512bc85ecd02c6d7ae0b78e98a8e5434] is to make machines
produced from 2012 to now not saving NVS region to accelerate S3.

But, Lenovo G40-45, a platform released in 2015, still needs NVS memory
saving during S3. A quirk is introduced for this platform.
