From: Mohammed Shafi Shajakhan <mohammed@xxxxxxxxxxxxxxxx>
Enable support for 'drv_sta_statistics' callback.
Export rx_duration support if available to cfg80211/nl80211
This can also act as a placeholder for any new per STA stats support

[v2] fixed condition for ath10k state
Dependencies:
1. cfg80211/nl80211: Add support for NL80211_STA_INFO_RX_DURATION
2. iw: Add support for NL80211_STA_INFO_RX_DURATION netlink
attribute
3. ath10k: Enable debugfs provision to enable Peer Stats feature
