[PATCH 4/9] arm64: tegra: Add I2C controllers on Tegra186

[Thierry Reding <thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Tegra186 has a total of nine I2C controllers that are compatible with
the I2C controllers introduced in Tegra114. Two of these controllers
share pads with two DPAUX controllers (for AUX transactions).
