qcacmn: Add CDP API to save low latency connection count

Browse Source 
The 11g and 11a connections are latency critical and
hence the tx coalescing cannot be applied on traffic
running for these connections.

Add a CDP API to save the number of low latency
connection in the dtapath vdev handle. The Software
latency manager can use this information to decide
and skip the tx register write coalescing for packet
transmission on low latency connections.
