hwrng: bcm2835 - Enable BCM2835 RNG to work on BCM63xx platforms
We have now incorporated all necessary functionality for the BCM63xx
platforms to successfully migrate over bcm2835-rng, so add the final
bits: Kconfig selection and proper platform_device device type matching
to keep the same platform device name for registration to work.
