arm64: tegra: Device tree changes for v5.18-rc1

Based on the for-5.18/dt-bindings changes, this adds various new
features on Tegra234 such as IOMMU, audio, gpio-keys, I2C and PWM
support.

Device trees for 64-bit Tegra boards are now also built with overlay
support enabled, which allows firmware to apply overlays and customize
the DTB that is passed to the kernel.

There are also a couple of cleanups and additions for older devices,
such as USB device mode support on Jetson Xavier NX.

* tag 'tegra-for-5.18-arm64-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
  arm64: tegra: Drop arm,armv8-pmuv3 compatible string
  arm64: tegra: Enable Jetson Xavier NX USB device mode
  arm64: tegra: Enable UART instance on 40-pin header
