Applied with re-ordering it, to keep it after ExynosAutov9. For the
future: don't add entries to the end of lists because it causes exactly
this issue we have here: unnecessary conflicts. Please keep this rule
for entire development, not only pinctrl.

If both you and Peter were observing this basic rule, I would not have
work of reshuffling and fixing conflicts.

Please check the result if I reshuffled/solved conflicts correctly.

Best regards,
Krzysztof
