PM / Runtime: Add second macro for definition of runtime PM callbacks
By having the runtime PM callbacks implemented for CONFIG_PM, these becomes available in all combinations of CONFIG_PM_SLEEP and CONFIG_PM_RUNTIME. The benefit using this, is that we don't need to implement the wrapper functions which handles runtime PM resourses, typically called from both runtime PM and system PM callbacks. Instead the runtime PM callbacks can be invoked directly from system PM callbacks, which is useful for some drivers, subsystems and power domains. Use the new macro SET_PM_RUNTIME_PM_OPS in cases were the above makes sense. Make sure the callbacks are encapsulated within CONFIG_PM instead of CONFIG_PM_RUNTIME. Do note that the old macro SET_RUNTIME_PM_OPS, which is being quite widely used right now, requires the callbacks to be defined for CONFIG_PM_RUNTIME. In many cases it will certainly be convenient to convert to the new macro above, but that will have to be distinguished in case by case.
