[CRYPTO] hifn795x: Disallow built-in hifn795x when HW_RANDOM is m
Currently it is possible to select HW_RANDOM as a module and have
hifn795x built-in. This causes a build problem because hifn795x
will then call hwrng_register which isn't built-in.
This patch introduces a new config option to control the hifn795x
RNG which lets us avoid this problem.
