Public bug reported:
[Impact]
This impacts 2 socket Cavium ThunderX systems using pass-1.1 silicon, and can
result in IO hangs.
[Test Case]
$ dmesg | grep "ITS command queue timeout"
[Regression Risk]
The workaround is in gicv3 specific code, and only activated when the hw
revision in the IIDR matches ThunderX pass 1.x silicon, so risk to other
platforms is minimal.
