Per the reference manal for the RZ/G Series, 2nd Generation, the RZ/G2M, RZ/G2N, and RZ/G2H have a bit that can be set to choose between a crystal oscillator and an external oscillator. Because only boards that need this should enable it, it's marked as disabled by default for backwards compatibility with existing boards. Signed-off-by: Adam Ford <aford173@gmail.com>
