gpio: tegra: Hide tegra_gpio_enable/disable()
Recent pinctrl discussions concluded that gpiolib APIs should in fact do
whatever is required to mux a GPIO onto pins, by calling pinctrl APIs if
required. This change implements this for the Tegra GPIO driver, and removes
calls to the Tegra-specific APIs from drivers and board files.
