OPP: Disallow "opp-hz" property without a corresponding clk

This removes the special code added by the commit 2083da24eb56 ("OPP:
Allow multiple clocks for a device"), to make it work for Qcom SoC.

In qcom-cpufreq-hw driver, we want to skip clk configuration that happens via dev_pm_opp_set_opp(), but still want the OPP core to parse the "opp-hz" property so we can use the freq based OPP helpers.

The DT for Qcom SoCs is fixed now and contain a valid clk entry, and we no longer need the special handling of the same in the OPP core. Update Qcom driver as well to disallow freq update to the clk.

Mani, can you give this a try again please, thanks ? I have only compile tested this.
