qcacmn: Add support to query RCPI info

RCPI is measure of received RF power in the selected channel for a
received frame and is measured at the antenna connector and shall be
measured over an entire frame. It is a monotonically increasing,
logarithmic function of received power level.

Wlan firmware computes RCPI.

Add host support to query firmware for RCPI information of
peer mac address in sta, p2p client, softap and p2p go modes.
