This set of patches introduces support for the new Tegra234 SoC, also
known as Orin. Currently no silicon of this chip is available, so the
support added here is for a simulation platform known as VDK.

Note that this simulation platform is not available publicly. However
the goal is to use the simulation platform as a way of upstreaming as
much support as possible ahead of tapeout.

Once actual silicon becomes available, the plan is to stop supporting
the simulation platform and shift focus to real hardware.
