cmake: clear BOARD_CACHE when invalid board identifier is given

Clear BOARD_CACHE when no or an invalid board identifier is provided on first CMake invocation. This allows users to re-run CMake and provide a valid board identifier as well as avoiding `BOARD` to be replaced with an invalid BOARD_CACHED value. Signed-off-by: Torsten Rasmussen <[email protected]>
