[PATCH v2 1/3] cfg80211: Extend avg ack rssi support for mgmt frames

[Balaji Pothunoori]

Defining APIs to update avg ack rssi irrespective of data or
mgmt tx ack packet; this patch keeps the original behavior
intact without breaking the existing API.

[PATCH v2 3/3] ath10k: management tx ack rssi capability check

[Balaji Pothunoori]

Adding WMI service check for management tx ack rssi support; this is
done to maintain common avg ack signal in user level for both data
and management tx ack packet.

Tested on QCA4019(fw version-10.4-3.2.1-00063).
