video: rockchip: vpu: introduce safe reset method

Even the same type video IP would request a different numbers
of reset control.

From the RK3328 times, the video IP also request decrease the
frequency of the clock to lower than 300 MHZ before resetting.
It seems no hard to apply it into the previous platform.
