[PATCH 2/2] crypto: crypto4xx - Avoid linking failure with HW_RANDOM=m

[Florian Fainelli]

It is currently possible to build CONFIG_HW_RANDOM_PPC4XX=y with
CONFIG_HW_RANDOM=m which would lead to the inability of linking with
devm_hwrng_{register,unregister}. We cannot have the framework modular
and the consumer of that framework built-in, so make that dependency
explicit.
