[PATCH v2 1/2] nvme-pci: Add TUXEDO InfinityFlex to Samsung sleep quirk

From: Georg Gottleuber <ggo at tuxedocomputers.com>

On the TUXEDO InfinityFlex, a Samsung 990 Evo NVMe leads to a high power
consumption in s2idle sleep (4 watts).

This patch applies 'Force No Simple Suspend' quirk to achieve a sleep with
a lower power consumption, typically around 1.4 watts.
