qcacmn: Add configuration interace for Lithium Datapath
Add a generic framework (wlan_cfg) for all configuration parameters (eg.number of tx/rx rings) used by DP. Define all the parameters as macro constants. We will later enhance wlan_cfg framework to read these parameters from device tree file or ini file and populate in DP config structures.
