net: ethernet: qualcomm: Initialize PPE queue management for IPQ9574

QM (queue management) configurations decide the length of PPE queues
and the queue depth for these queues which are used to drop packets
in events of congestion.

There are two types of PPE queues - unicast queues (0-255) and multicast
queues (256-299). These queue types are used to forward different types
of traffic, and are configured with different lengths.
