qcacmn: Add support in DP for enabling multiqueue support

Enable multiqueue on VAP with 4 Tx and Rx queues in lithium.

In Rx path set the rx queue of skb based on the reo ring id on which it
is received.

In Tx path use the queue_mapping of skb to map to the hardware Tx ring
on which it has to be transmitted.
