The included options should depend on CRYPTO_DEV_NX since currently CRYPTO_DEV_NX cannot be built for little endian. While Kconfig appears to understand this convoluted dependency situation, it isn't explicitly stated. This patch addresses the missing dependencies for CRYPTO_DEV_NX_ENCRYPT and CRYPTO_DEV_NX_COMPRESS which should depend on CRYPTO_DEV_NX. It also makes more sense to put all three options into the nx/Kconfig file and have the file included unconditionally.
