Seems that some device trees have "/soc" and others "/soc@0". For at
least a little context, see commit a1875bf98290 ("arm64: dts: qcom:
sdm845: Add unit name to soc node"). Since (presumably) this would
only be for newer SoCs then I guess you should search for "/soc@0"?
...and then if we ever have a SoC that's not @0 then we would have to
iterate through all SoCs
