In this case, the NPCM RNG driver also provides some of the functions that are implemented in the generic LIB_RAND file, so only allow this to be built when that is disabled. The exynos RNG driver depends on ARM SMCCC calls and so cannot be built outside of that. Express these requirements in Kconfig as well.
