Selecting CRYPTO_DEV_NX causes a conditional include of nx/Kconfig but
options within nx/Kconfig do not depend on it. 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.
