Newer qcom chips support newer versions of the qce IP, so add new compatible strings for qcom-qce (in addition to the existing "qcom,crypto-v5.1"). With [1], Thara tried to add the support for new compatible strings, but we couldn't conclude on the approach to be used. Since we have a number of new qcom arm64 SoCs available now, several of which support the same crypto IP version, so it makes more sense to use the IP version for the compatible string, rather than using the soc name as the compatible string.
