Bug description:
  [Impact]

   * NVMe devices are not recognized by lshw in Ubuntu

  [Test Case]

   * Running "lshw -C disk" or "lshw -C storage" does not show NVMe devices.
     Example: https://pastebin.ubuntu.com/p/FfKGNc7W6M/

  [Where problems could occur]

   * This upload consists of four cherry-picked patches and the feature
  is self-contained, so the regression potential is quite low. If
  there's anything to happen, it would be in the network device scan,
  where the structure was altered by the main NVMe patch.

  * For those who does HW monitoring/inventory listing based on 'lshw'
  might observe changes in their inventory listing, it shouldn't be a
  'problem' but I want to point this out.

  [Other information]

  # Redhat bug:
  https://bugzilla.redhat.com/show_bug.cgi?id=1695343

  * It also seems to fit in the 'other safe cases':

  https://wiki.ubuntu.com/StableReleaseUpdates#Other_safe_cases
  For Long Term Support releases we regularly want to enable new hardware. Such changes are appropriate provided that we can ensure not to affect upgrades on existing hardware.
