Patch 1 adds the binding for the NVIDIA GB200-UT3.0b platform.
Patch 2 adds the device tree for the NVIDIA GB200-UT3.0b platform.
This is an Aspeed AST2600 based unit testing platform for GB200.
UT3.0b is different than nvidia-gb200nvl-bmc due to networking topology
differences, additional gpio expanders, and voltage regulator gating
some devices.
Reference to Ast2600 SOC [1].
Reference to Blackwell GB200NVL Platform [2].
