imx8ulp_evk: disable overflow of port0 for LPAV

Bit0: Port 0 behavior when bandwidth maximized. Set to 1 to allow overflow

With overflow set, we see some issue that A35 may not able to get enough
bandwidth and A35 will report hrtimer takes too much time, workqueue
lockup. With overflow cleared, the issues are gone.
