[PATCH v6 13/26] PM / devfreq: rockchip-dfi: Pass private data struct to internal functions

The internal functions do not need the struct devfreq_event_dev *,
so pass them the struct rockchip_dfi *. This is a preparation for
adding perf support later which doesn't have a struct devfreq_event_dev *.
