ath11k: Register DBR event handler for CFR data
Firmware sends an WMI event WMI_PDEV_DMA_RING_BUF_RELEASE_EVENT to host to indicate the CFR data availability in the DB ring. Host will reap the CFR data from the DB ring buffers and invoke correlate_and_relay API to correlate the CFR data with the meta data coming from the other WMI event WMI_PEER_CFR_CAPTURE_EVENT. If correlate and relay function returns success then release the buffer to user space through relayfs, otherwise hold the buffer until other WMI event comes from the firmware. Tested-on: IPQ8074 WLAN.HK.2.5.0.1-00991-QCAHKSWPL_SILICONZ-1 Signed-off-by: Venkateswara Naralasetty <quic_vnaralas@quicinc.com>
