nvme-pci: Add TUXEDO InfinityFlex to Samsung sleep quirk

commit dbf2bb1a1319b7c7d8828905378a6696cca6b0f2 upstream.

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.
