BugLink: https://bugs.launchpad.net/bugs/1933518


* Microchip asks to update the SCSI SmartPQI driver to latest version
  from upstream Linux kernel.
* This contains mostly fixes and refactorings.
* Updated driver allows to support properly latest SmartPQI controllers.


* Cherry-pick all the patches related to smartpqi.
* These are clean picks although the patchset is pretty big.

[Test Plan]

* Build-test each commit.
* Asked Microhip to perform the testing. Received feedback:
  "I installed the provided kernel package and thus far performed:
  1. reboot tests
  2. insmod/rmmod tests
  3. fio testing: no performance regressions"

[Where problems could occur]

* The patches touch only smartpqi driver so the scope of possible
  failures is limited to systems which probe it (so basically systems
  with SmartPQI controller).
* On such SmartPQI-equipped systems the patchset can cause data corruption,
  data loss or unavailability of SCSI storage and boot failure.
