Ouch. I didn't check from pinctrl but I see those should be converted
as well. I'm a bit short on time right now so if anyone else is
interested I won't mind :)

Luckily the value for IN and OUT is not changed - only the defines were
added - so all of the drivers do not need to be done at once. If no one
else will take the pinctrl part then I can probably do pinctrl patches
for v5.6 cycle.
