[PATCH] CHROMIUM: devfreq: rk3399: Clear edev->dev drvdata before enabling dfi

[Jeffy Chen]

Currently we are using edev->dev drvdata to get rk3399-dmc data, but
it would be inited to edev in devfreq_event_add_edev.

So we need to clear the edev->dev drvdata before enabling dfi, to
prevent dfi from getting the wrong rk3399-dmc data when the irq
triggered too early.
