Subject: [PATCH v2] Added QUIRKs for ADATA XPG SX8200 Pro 512GB

 Booting with default_ps_max_latency_us >6000 makes the device fail.
 Also SUBNQN is NULL and gives a warning on each boot/resume.
  $ nvme id-ctrl /dev/nvme0 | grep ^subnqn
    subnqn    : (null)

 I use this device with an Acer Nitro 5 (AN515-43-R8BF) Laptop.
 To be sure is not a Laptop issue only, I tested the device on
 my server board too with the same results.
 ( with 2x,4x link on the board and 4x on a PCI-E card ).
