nvme-pci: mark Kingston SKC2000 as not supporting the deepest power state
commit dc22c1c upstream My 2TB SKC2000 showed the exact same symptoms that were provided in 538e4a8 ("nvme-pci: avoid the deepest sleep state on Kingston A2000 SSDs"), i.e. a complete NVME lockup that needed cold boot to get it back. According to some sources, the A2000 is simply a rebadged SKC2000 with a slightly optimized firmware. Adding the SKC2000 PCI ID to the quirk list with the same workaround as the A2000 made my laptop survive a 5 hours long Yocto bootstrap buildfest which reliably triggered the SSD lockup previously.
