And why is SoC specific compatible required here ? Is the implementation on
sm8350 any different than the ones using "qcom,cpufreq-epss" compatible ?

FWIW, the same compatible string must be reused until the time there is
difference in the hardware. The compatible string must be considered as a marker
for a particular version of the hardware.
