From: Mohammed Shafi Shajakhan <mohammed@qti.qualcomm.com>
Provide a debugfs entry to enable/ disable Peer Stats feature.
Peer Stats feature is for developers/users who are more interested
in studying in Rx/Tx stats with multiple clients connected, hence
disable this by default. Enabling this feature by default results
in unneccessary processing of Peer Stats event for every 500ms
and updating peer_stats list (allocating memory) and cleaning it up
ifexceeds the higher limit and this can be an unnecessary overhead
during long run stress testing.

Hi Kalle,
I had resent this change (to avoid any confusions with compilation issues)
as a part of the below series
[PATCH v1 1/3] ath10k: Enable debugfs provision to enable Peer Stats feature
[PATCH v1 2/3] ath10k: Introduce Extended Resource Config support
for 10.4
[PATCH v1 3/3] ath10k: Enable parsing per station rx duration for
10.4
Please let me know if there are any issues.
thanks,
shafi
