arm64: tegra: Device tree changes for v6.5-rc1

This introduces support for the IGX Orin and Jetson Orin Nano devices
and enables various additional features on the Jetson AGX Orin and
Jetson Orin NX. This also enables some basic thermal support to prevent
the devices from overheating.

Support for the GPU on the Google Pixel C is enabled and various minor
issues are fixed and cleaned up.
