[PATCH 6/9] arm64: tegra: Add GPIO controllers on Tegra186

From: Thierry Reding <treding at nvidia.com>
Tegra186 has two GPIO controllers that are no longer compatible with the
controller found on earlier generations. One of these controllers exists
in an always-on partition of the SoC whereas the other can be clock- and
powergated.
