arm64: tegra: Device tree changes for v6.6-rc1

The majority of this is fixes all over the place for DT schema
validation warnings. However, there are also cleanups for some things in
DT and audio support is added on IGX Orin. Jetson Orin NX and Nano also
gain a new thermal trip point to help keep the device cool at moderate
loads.
