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

Browse source

The BM (Buffer Management) config controls the pause frame generated
on the PPE port. There are maximum 15 BM ports and 4 groups supported,
all BM ports are assigned to group 0 by default. The number of hardware
buffers configured for the port influence the threshold of the flow
control for that port.
