Subject: [PATCH v3 3/4] arm64: dts: qcom: ipq9574: update TRNG compatible

RNG hardware versions greater than 3.0 are Truly Random Number
Generators (TRNG). In IPQ9574, the RNGblock is a TRNG.

This patch corrects the compatible property which correctly describes
the hardware without making any functional changes
