The GPIO controllers are enabled by default, so there's no need to
explicitly enable them.
Yup. I'll remove this patch.
Since I didn't see 'status' entry in GPIO nodes in tegra194.dtsi file, I thought
it means 'disabled'. But, contrary to my understanding, absence of 'status' entry
seems to mean 'okay'.
