ZOOM2 detect the version of the zoom2 board at runtime.
There are currently 3 versions of the zoom2 board.
The production board, that is currently being released.
The beta board, similar in form to the production board but not released.
The alpha board, a set of PCBs with a very limited circulation.
GPIO 94 is used to determine the version of the board. If GPIO 94 is clear,
the board is a production board, otherwise it is a beta board.
The alpha board will likely be mistaken for a beta board. An alpha board
was unavailible for testing.
This has been tested on the beta and production boards.
