CPUFREQ custom functions for OPP (Operating Performance Points) currently exist inside the OPP library. These custom functions currently depend on internal data structures to pick up OPP information to create the cpufreq table. For example, the cpufreq table is created precisely in the same order of how OPP entries are stored inside the list implementation. This kind of tight interdependency is purely artificial since the same functionality can be achieved using the generic OPP functions meant to do the same. This interdependency also limits the independent modification of cpufreq and OPP library. So use the generic dev_pm_opp_find_freq_ceil function that achieves the table organization as we currently use. As a result of this, we dont need to use the internal device_opp structure anymore, and we hence we can switch over to rcu lock instead of the mutex holding the internal list lock. This breaking of dependency on internal data structure imposes no change to usage of these. NOTE: This change is a precursor to moving this cpufreq specific logic out of the generic library into cpufreq.
