pinctrl: tegra: define GPIO compatible node per SoC
Tegra 2 uses a different GPIO controller which uses "tegra20-gpio" as
compatible string.
Make the compatible string the GPIO node is using a SoC specific
property. This prevents the kernel from registering the GPIO range
twice in case the GPIO range is specified in the device tree.
Fixes: 9462510ce31e ("pinctrl: tegra: Only set the gpio range if needed")
