parentPM / OPP: Make _find_opp_table_unlocked() static (diff)

PM / OPP: Expose _of_get_opp_desc_node as dev_pm_opp API
Rename _of_get_opp_desc_node to dev_pm_opp_of_get_opp_desc_node and add it to include/linux/pm_opp.h to allow other drivers, such as platform OPP and cpufreq drivers, to make use of it.
