Instead of having SoC name "qcom,sm8450-prng-ee" we could use "qcom,rng-ee" as

changed to "rng". Clock configuration is not needed on sm8550 as well. So it is
better to use generic compatible string.

Sorry for digging out this old thread, but I can't seem to find
supporting evidence for this, at least described in a in-your-face
way..

Can we determine whether the RNG generates pseudo-random numbers based
on a version number, or some other register? Would RNGv3.0 be a good
check?

I see that today we describe kodiak and talos marked as having a TRNG,
but they're much much older than 8450..
