Tegra: I2C: Add T114 clock support to tegra_i2c driver
T114 has a slightly different I2C clock, with a new (extra) divisor in standard/fast mode and HS mode. Tested on my Dalmore, and the I2C clock is 100KHz +/- 3Hz on my Saleae Logic analyzer. Added a new entry in compat_names for T114 I2C since it differs from the previous Tegra SoCs. A flag is set when T114 I2C HW is found so new features like the extra clock divisor can be used.
