hwrng: Fix a few driver dependencies and defaults
HW_RANDOM_ATMEL should not only default to ARCH_AT91, it should depend on it. This driver is useless on other architectures. Likewise, HW_RANDOM_EXYNOS should depend on ARCH_EXYNOS, as it it useless on other architectures. Also set the default to HW_RANDOM for the few architecture-specific drivers which didn't have it yet, for consistency.
