Revert "clk: Fix invalid execution of clk_set_rate"

This reverts commit 25f1c96a0e.

The offending commit results in errors like

	cpu cpu0: _opp_config_clk_single: failed to set clock rate: -22

spamming the logs on the Lenovo ThinkPad X13s and other Qualcomm
machines when cpufreq tries to update the CPUFreq HW Engine clocks.

As mentioned in commit 4370232c72 ("cpufreq: qcom-hw: Add CPU clock
provider support"):

	[T]he frequency supplied by the driver is the actual frequency
	that comes out of the EPSS/OSM block after the DCVS operation.
	This frequency is not same as what the CPUFreq framework has set
	but it is the one that gets supplied to the CPUs after
	throttling by LMh.

which seems to suggest that the driver relies on the previous behaviour
of clk_set_rate().

Since this affects many Qualcomm machines, let's revert for now.
