LS1043A DPAA work queue strict-only scheduling in a channel

In LS1043A DPAA hardware, current work queue (WQ) scheduling follows two level scheduler schema, which is mixture of strict and round-robin prioritization.

Is somehow possible to simplify the DPAA approach and use only 8 strict priorities with round robin completely disabled? (WQ 0 -> Priority 0, WQ 1 -> Priority 1, WQ 2 -> Priority 2, ..., WQ 7 -> Priority 7. Higher priority WQ has absolute strict priority over all lower priority WQs)

It is not possible to use 8 strict priorities. In other words, it's not possible to disable round robin selection that is used for medium and low priority tiers.
