nvme-pci: Add TUXEDO InfinityFlex to Samsung sleep quirk
commit dbf2bb1 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.
