net: ethernet: qualcomm: Initialize PPE RSS hash settings

The PPE RSS hash is generated during PPE receive, based on the packet
content (3 tuples or 5 tuples) and as per the configured RSS seed. The
hash is then used to select the queue to transmit the packet to the
ARM CPU.

This patch initializes the RSS hash settings that are used to generate
the hash for the packet during PPE packet receive.
