Subject: [PATCH] exynos-rng: Depend on ARCH_EXYNOS

The exynos-rng device is only found on Samsung EXYNOS devices but has
dependencies that allow it to be built on other architectures. This
can result in build failures on powerpc due to a missing clk_devm_get.

This patch makes it depend on ARCH_EXYNOS.
