gpio: tegra: implement gpio_request and gpio_free.

Recent pinctrl discussions concluded that gpiolib APIs
should in fact do whatever is required to mux a GPIO onto
pins.
This change is based on the work done by Stephen Warren in mainline
kernel.

    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.
