From: Georg Gottleuber <ggo@tuxedocomputers.com>

On the TUXEDO InfinityBook S Gen8, a Samsung 990 Evo NVMe leads to
a high power consumption in s2idle sleep (3.5 watts).

This patch applies 'Force No Simple Suspend' quirk to achieve a sleep with
a lower power consumption, typically around 1 watts.
