Dropped the DT patch now.

Mani, I believe the first patch in this series is still required.
Without that, when the cpufreq driver calls dev_pm_opp_set_opp(), the
OPP core may end up calling clk_set_rate(), which shouldn't be done in
case of Qcom SoCs.

I am not sure though, how it will work with sc8280xp. Can you please
check ?
