nvme-pci: Add sleep quirk for Kingston drives

Browse source

commit 107b4e063d upstream.

Some Kingston NV1 and A2000 are wasting a lot of power on specific TUXEDO
platforms in s2idle sleep if 'Simple Suspend' is used.

This patch applies a new quirk 'Force No Simple Suspend' to achieve a
low power sleep without 'Simple Suspend'.
