[ Upstream commit 4e435a9dd26c46ac018997cc0562d50b1a96f372 ]
Remove the .set_parent method in clk_pm_cpu_ops.
This method was supposed to be needed by the armada-37xx-cpufreq driver, but was never actually called due to wrong assumptions in the cpufreq driver. After this was fixed in the cpufreq driver, this method is not needed anymore.
