Target copies spectral report and CFR report through dbring to host for further processing. This mechanism involves ring and buffer management in the Host, FW, and uCode, where improper tail pointer update issues are seen. This dbring debug support help to debug such issues by tracking head and tail pointer movement along with the timestamp at which each buffer is received and replenished. Provide a debugfs interface to enalbe/disable dbring debug support and dump the dbring debug entries. Also introduced a new hardware param to add dbring debugfs support for few hardwares which are using dbings. Usage: echo <dbr_id> <val> > /sys/kernel/debug/ath11k/ipq8074_2/ mac0/enable_dbr_debug dbr_id: 0 for spectral and 1 for CFR val: 0 - disable, 1 - enable.
