GPIO fixes for the v5.4 series: 

- Fix a build error in the tools used for kselftest.
 - A series of reverts to bring the Intel Merrifield back to
   working. We will likely unrevert the reverts for v5.5
   but we can't have v5.4 broken.

Pull GPIO fixes from Linus Walleij:
 "More GPIO fixes! We found a late regression in the Intel Merrifield
  driver. Oh well. We fixed it up.

   - Fix a build error in the tools used for kselftest

   - A series of reverts to bring the Intel Merrifield back to working.

  We will likely unrevert the reverts for v5.5 but we can't have v5.4
  broken"
