Commit 69b6f2e817e5b ("crypto: arm64/aes-neon - limit exposed routines if faster driver is enabled") intended to hide modes from the plain NEON driver that are also implemented by the faster bit sliced NEON one if both are enabled. However, the defined() CPP function does not detect if the bit sliced NEON driver is enabled as a module. So instead, let's use IS_ENABLED() here.
