Fortunately, the switch frequency support isn't released, so we can modify it now without any concern.

The difference between MP8867 and MP8869 are: 1.If V_BOOT, the vref of MP8869 is fixed at 600mv while vref of MP8867 is determined by the I2C control. 2.For MP8867, when setting voltage, if the step is within 5, we need to manually set the GO BIT to 0.
