Subject: [PATCH 1/2] ath10k: Add support for ath10k_sta_statistics support

From: Mohammed Shafi Shajakhan <[email protected]>

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

1. cfg80211/nl80211: Add support for NL80211_STA_INFO_RX_DURATION
2. iw: Add support for NL80211_STA_INFO_RX_DURATION netlink
