This adds a driver for the Tegra pinmux, and required parameterization data for Tegra20 and Tegra30. The driver is initially added with driver name and device tree compatible value that won't cause this driver to be used. A later change will switch the pinctrl driver to use the correct values, switch the old pinmux driver to be disabled, and update all code that uses the old pinmux APIs to use the new pinctrl APIs.
