tegra20: add pinctrl driver
This adds a pinctrl driver for the Tegra 20 line of SoCs. It only
supports the three basic pinconfiguration settings function mux,
tristate control and pullup/down control.
The driver understands the same devicetree bindings as the Linux one,
unimplemented pinconfiguration options will be ignored.
