OPP: Add dev_pm_opp_set_config() and friends
The OPP core already have few configuration specific APIs and it is
getting complex or messy for both the OPP core and its users.
Lets introduce a new set of API which will be used for all kind of
different configurations, and shall eventually be used by all the
existing ones.
The new API, returns a unique token instead of a pointer to the OPP
table, which allows the OPP core to drop the resources selectively later
on.
