dt-bindings: Add Tegra PMC pad configuration bindings Document the PMC pinctrl bindings for pad power state and signaling voltage configuration. Both nvidia,tegra186-pmc.txt and nvidia,tegra20-pmc.txt are modified as they both cover SoC generations for which these bindings apply. Add a header defining Tegra PMC pad voltage configurations.
