dpaa_eth: Pass the portal info to the QMan APIs for NAPI scheduling.
Pass the portal info via callbacks in order to call the new qman apis for napi
schedule and napi poll, thus follow the portal to disable its DQRI or enable
DQRI for NAPI, regardless the portal is migrated to other cpu (in hotplug case)
or not.
