ARM: tegra: add GPIO initialization table function The HW-defined procedure for booting Tegra requires that some pins be set up as GPIOs immediately at boot in order to avoid glitches on those pins, when the pinmux is programmed. Add a feature to the GPIO driver which executes a GPIO configuration table. Board files will use this to implement the correct HW initialization procedure.
