Only the Tegra114 value should be listed here; the presence of the
Tegra30 value in the upstream kernel is a mistake that will be fixed as
part of the Tegra114 clock driver patches.

Same here; only include the Tegra114 value since the HW isn't 100%
compatible with the Tegra20 HW.

According to our downstream Linux kernel, that I2C controller can run up
to 400KHz on this board.
