ARM: tegra: convert CONFIG_TEGRA_GPIO to Kconfig
Future chips will contain different GPIO HW. This change will enable future SoC support to select the appropriate GPIO driver for their HW, in a future-looking fashion, using Kconfig. TEGRA_GPIO is not simply selected by TEGRA_COMMON (even though all current Tegra chips used this GPIO HW) to simplify the later addition of support for Tegra SoCs that use different GPIO HW.
