arm64: tegra: Device tree changes for v5.7-rc1

These changes add support for the XUSB pad controller, as well as the
XUSB controller on Tegra194. Furthermore, USB device mode is supported
across Tegra210 and Tegra186 boards. PCIe endpoint mode support is added
for the Jetson AGX Xavier platform.

Various minor fixes eliminate warnings on boot related to missing power
supplies for some devices.
