Public bug reported: == SRU Xenial == Pick up the following device quirk to resolve a hardware/firmware bug affectung some NVMe drives that use the PM1725 controller. Under adverse circumstances the bug can result in data corruption and loss.

Thus a delay is needed before checking whether the controller is ready. Note that the admin queue depth is also limited to 64 on older versions of this board. Since our NVME_AQ_DEPTH is now 32 that is no longer an issue. Signed-off-by: Martin K.
