Channel Frequency Response(CFR) captures FFT bins corresponding to a PPDU received and this is relayed to user space application along with additional information about the PPDU gathered in the host. Usecases of this feature include location sensing, motion detection. Change-Id: If0da492bc1fcc0fc2b6e42339c56f9a54ee813f7 CRs-Fixed: 2541307
