Use subject prefixes matching the subsystem (git log --oneline -- ...),
so it is rng, not RNG. Also, you are not adding all-Rockhip RNG but a
specific device.
Subject: drop second, redundant "bindings".

These are too vague names. Everything is a clk in clock-names, so no
need usually to add it as name suffix. Give them some descriptive names,
e.g. core and ahb.
