arm64: tegra: Add pin control states for I2C on Tegra186
Two of the Tegra I2C controllers share pads with the DPAUX controllers. In order for the I2C controllers to use these pads, they have to be set into I2C mode. Use the I2C and off pin control states defined in the DT nodes for DPAUX as "default" and "idle" states, respectively. This ensures that the I2C controller driver can properly configure the pins when it needs to perform I2C transactions.
