Subject: [PATCH v2 1/7] Revert "dt-bindings: crypto: qcom,prng: Add SM8450"

This reverts commit b9296bb41275 ("dt-bindings: crypto: qcom,prng: Add SM8450"),
since the RNG HW on the SM8450 SoC is in fact a True Random Number Generator,
a more appropriate compatible should be instead as reported at [1].
