gpio: tegra: fix irq_release_resources calling enable instead of disable

tegra_gpio_irq_release_resources() erroneously calls tegra_gpio_enable()
instead of tegra_gpio_disable(). When IRQ resources are released, the
GPIO configuration bit (CNF) should be cleared to deconfigure the pin as
a GPIO. Leaving it enabled wastes power and can cause unexpected behavior
if the pin is later reused for an alternate function via pinctrl.
