Currently, the calculation of ack signal strength is incorrect.
This is because before calculating the ack signal strength, ath11k need
to determine whether the hardware and firmware support db2dbm. If the
hardware and firmware support db2dbm, do not need to add noise floor,
otherwise, need to add noise floor.
Besides, the value of ack_rssi passed by firmware to ath11k should be a
signed number, so change its type to s8.
After that, "iw wlan0 station dump" show the correct ack signal strength.
Such as:
root@CDCCSTEX0799733-LIN:~# iw wlp88s0 station dump
