hwrng: histb - Move driver to drivers/char/hw_random/histb-rng.c
Move to drivers/char/hw_random since histb-(t)rng does not provide
cryptography pseudo rng.
histb-rng is pretty like hisi-rng, but after investigation, we confirm
there is no RNG_PHY_SEED register on histb-rng so a separate driver is
needed.
Still we rename relevant function names to match those in hisi-rng.
