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.
