qcacmn: Add cdp support four address raw mode simulation

Browse Source 
Added cdp interface support for raw mode simulation code to support 4 address
frames. This function finds the fourth address of the packet.

* @brief encap nbuf(s) from Ethernet II format to 802.11 Raw format
* @details
* Note that in the case of IP fragments, the function takes two fragments at a
* time and creates an A-MSDU. If it has seen the first of such fragments, it
* returns 0 to indicate that it needs to consume one more. In this case, the
* caller shouldn't pass the nbuf to lower layers.
* The function is simple and doesn't dynamically take decisions on A-MSDU
* formation. It can be extended to pack more fragments into an A-MSDU if
* required, but in this case there can be greater losses due to the
* environment. The objective of the function is only to simulate regular
* scatter/gather.
* @brief finds the ast entry for the packet
* @details: Finds the ast entry i.e 4th address for the packet based on the
* details in the netbuf.
*
* @param vdev - the data virtual device object
* @param pnbuf - pointer to nbuf
* @param raw_ast - pointer to fill ast information
*
* @return - 0 on success, -1 on error, 1 if more nbufs need to be consumed.
