qcacmn: Add support to improve coex logging

Add support to get the various Coex data from the debugfs.
This commit adds the support to get the various coex data:
            * COEX STATE
            * COEX DPWB STATE
            * COEX TDM STATE
            * COEX IDRX STATE
            * COEX ANTENNA SHARING STATE

The specific state information can be read via the debugfs.

Example to read the COEX STATE logging:
            sm6150:/ # echo "1" > /d/wlan/mws_coex_status_info
            sm6150:/ # cat /d/wlan/mws_coex_status_info
                    Reading for command MWS_COEX_STATE.
                    vdev_id = 0
                    coex_scheme_bitmap =  0
                    active_conflict_count = 0
                    potential_conflict_count = 0
                    chavd_group0_bitmap = 0
                    chavd_group1_bitmap = 0
                    chavd_group2_bitmap = 0
                    chavd_group3_bitmap = 0
