Configure fine timing measurement (FTM) responder role from the
ftm_responder bss param sent by mac80211. With FTM functionality
offloaded to firmware, adding the interface allows userspace
to enable FTM responder functionality. ath10k disables it at the
time of interface creation.
Supported FW: 10.4
Tested on QCA9984 with firmware: 10.4-3.6-00144
