tegra: Implement gpio_early_init() on Tamonten
The PI4 GPIO is used on Tamonten to reset carrier board peripherals. Power sequencing hardware on the carrier pulls the reset low before powering up the Tegra, and the CPU is supposed to signal readiness, and therefore bring peripherals out of reset by pulling PI4 high.
