Series hwmon (it87): Correct handling for configuration mode | expand

Remove DMI tests for boards that are known to have issues with entering
configuration mode, as now we are testing the chips directly and no
longer need to rely on matching the board.

Leave the DMI table in place, for the nVIDIA board, and any future
expansions.

v2:
 * no change.

v3:
 * no change.
