According to the Tegra TRM, GPIOs are aggregated into /ports/ of 8 GPIOs, not into /banks/. Fix <dt-bindings/gpio/tegra-gpio.h> to correctly reflect this naming convention. While this seems like silly churn, it will become slightly more important once we introduce the GPIO binding for upcoming Tegra chips.
