MLK-14301: Revert "MLK-11343-01 cpufreq: imx: replace clk_get & regulator_get will devm ones"

Upstream rejected this patch because it is wrong: Attaching clk and
regulator resources to the cpu device results in them never actually
getting freed.

This is relevant now that we rely on supporting EPROBE_DEFER because we
must handle correctly returning from a partial probe.

In particular this patch fixes imx6qp-sabresd not setting the PU
regulator to bypass mode because the cpufreq driver fetched the
regulator before gpc and leaked it.

This is not a straight revert because other clks and regulators were
added, we add code to free them too.
