    This patch refines OV mipi camera reset sequence according to
    OV's recommendation:
    reset --------------------|_____|----------------
                            ->| 1ms |<-
    pwdn  ----------|_________________________|------
                  ->|   5ms   |<- ->|   5ms   |<-
        ->|   5ms   |<-
    This change makes the OV mipi camera be at a correct status
    after reset, otherwise, the wrong status of OV mipi camera
    will reduce the ~2.78V analog camera power to ~2.3V, which
    causes random thin colorful lines on OV5642 CSI camera image
    as OV5642 CSI camera uses the same analog power.
