imx8ulp_evk: Update DDR ports arbitration for DCNANO underrun

To resolve DCNANO underrun issue, change the DDR Port 0 arbitration
from round robin fashion to fixed priority level 1, while other ports
are not assigned any priority, so they will be serviced in round robin
fashion if there is no active request from Port 0.
