Subject: [PATCH 0/3] Introduce PRNG on SM8450

SM8450's PRNG seems to be the same good ol' IP, except without a core
clock.

For a lack of a better idea on how to test it, /proc/crypto reports that
the selftest has gone through..

Subject: [PATCH 1/3] dt-bindings: crypto: qcom,prng: Add SM8450

SM8450's PRNG does not require a core clock reference. Add a new
compatible with a qcom,prng-ee fallback and handle that.
