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

Browse Source 
[ Upstream commit 4b7ef7b05afcde44142225c184bf43a0cd9e2178 ]

[821d6f0359] 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.
