`amplc_dio200_common_detach()` doesn't do much apart from freeing the IRQ handler that was requested by `amplc_dio200_common_attach()` if `dev->irq` is non-zero. There is no need to check if the pointer to the constant board data or the pointer to private per-device data exist, so remove those tests.
