Reserve GPIO pins 85-88 as these aren't meant to be accessible from the
application CPUs (causes reboot). Yet another fix similar to
9134586715e3, 5f8d3ab136d0, which is needed to allow angler boot after
3edfb7bd76bd ("gpiolib: Show correct direction from the beginning").

Changes v1->v2:
* Remove <0 4> (not needed)
* Remove from commit message: Fixes: 3edfb7bd76bd ("gpiolib: Show
correct direction from the beginning") - although fix is needed after
3edfb7bd76bd, I'm not sure if this commit is to blame commits which
added/modified DTS.
Kind regards,
Petr
