Refactor the gb200 logic to be separate
Refactors the gb200 logic to be in its own file, and folder.
This way we can specify folder level owners more easily and separate
concerns for different companies using this repo. Also keeps
platform.cpp relatively clean
Tested:
Flashed onto a gb200, log output was clean
