ARM: tegra: add I2C nodes to Tegra114 DT
NVIDIA's Tegra114 has 5 I2C controllers. These controllers have the following changes which makes incompatible with previous hardware: - Single clock source to I2C controller. - Interrupt support for per packet transfer. Add DT entry for I2C controllers and make it compatible with "nvidia,tegra114-i2c".
