dt-bindings: i2c: nvidia,tegra20-i2c: Add Tegra256 I2C compatible
Add compatible for Tegra256 I2C controllers. Tegra256 consists of
8 generic Tegra I2C controllers similar to previous generations.
The parent clock frequency is different in these controllers and
hence the timing parameter values are different from the previous
ones.
