PM / OPP: list_del_rcu should be used in function _remove_opp_dev
list_del_rcu should be used to replace list_del in function _remove_opp_dev,
since the opp is a rcu protected pointer.
Test: for example, on an ARM big.Little platform, the opp_table of big cluster
will be removed when big cluster is removed, which should be implemented in
the cpufreq driver.
Then a stress test that the big cluster is plugged in/out, can test the patch.
