Revision 3
----------
See commit ID `3b6b283eabe7a655c861d1543aeae49d27566f53` and the two commits
before that.
This revision disables PCI-E Re-plug (hotplug feature) for the NVMe SSD on
Dell OptiPlex 3050 Micro, to prevent the device from being renamed randomly;
such renaming will cause a system crash if booting Linux from the NVMe.
In my case, I was running RAID1 (SATA+NVMe) and every few days, the RAID1 got
unsynced; I simply re-synced and it was fine, but what if that was a RAID0? It
would possibly corrupt the entire array.
This revision should prevent the issue from occuring. Without this patch,
the `nvme0n1` device (as an example) might randomly rename to `nvme0n2`, because
Linux would see it as a new device.
This same fix was made to the ThinkPad T480/T480s to fix the same issue there,
which manifested during S3 resume, but that bug never made it into the release
because it was fixed *before* the initial release of Libreboot 20241206.
