Bug description:
[Impact]
On deployments with lots of disks, timeouts can occur that escalate into
nexus resets. This can cause disk devices to disappear from the system,
possibly requiring a reboot to recover:

[Test Case]
This was seen on a system with 100s of disks, something I don't have access
to, so verification testing will be regression-only.
[Fix]
A fix queued in the scsi maintainer's tree adjusts some magic registers in
the controller, and that somehow fixes the problem (I don't have programming
docs for this controller, so I can only hand-wave here).
[Regression Risk]
The fix is localized to the hisi_sas_v3_hw driver, which is only used in
Ubuntu for the D06 platform.
