    drivers/nvme: Add quirks for device 126f:2262
    
    [ Upstream commit e89086c43f0500bc7c4ce225495b73b8ce234c1f ]
    
    This commit adds NVME_QUIRK_NO_DEEPEST_PS and NVME_QUIRK_BOGUS_NID for
    device [126f:2262], which appears to be a generic VID:PID pair used for
    many SSDs based on the Silicon Motion SM2262/SM2262EN controller.
    
    Two of my SSDs with this VID:PID pair exhibit the same behavior:
    
      * They frequently have trouble exiting the deepest power state (5),
        resulting in the entire disk unresponsive.
        Verified by setting nvme_core.default_ps_max_latency_us=10000 and
        observing them behaving normally.
      * They produce all-zero nguid and eui64 with `nvme id-ns` command.
    
    The offending products are:
    
      * HP SSD EX950 1TB
      * HIKVISION C2000Pro 2TB
