qcacmn: CFR: Monitor/Data ring filter settings

Channel Frequency Response(CFR) captures FFT bins corresponding to a PPDU
received and this is relayed to user space application. Since FFT bins
alone will not be meaningful, additional information about the PPDU such
as Peer addr, BW, NSS, etc are extracted from multiple PPDU status TLVs
and passed on to userspace along with CFR data.

Host RX monitor status ring is configured during CFR enable and the host
subscribes to relevant PPDU TLVs that provides all necessary information
for CFR data correlation.
