[PATCH] crypto: exynos - fix Wvoid-pointer-to-enum-cast warning

[Krzysztof Kozlowski]

'type' is an enum, thus cast of pointer on 64-bit compile test with W=1
causes:

  exynos-rng.c:280:14: error: cast to smaller integer type 'enum exynos_prng_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
