Subject: [PATCH] ath9k: enabled MFP capability unconditionally
ath9k will already fallback on software-crypto for chipsets not
supporting IEEE802.11w (MFP). So advertising MFP is not dependent
on disabling HW crypto for all traffic entirely.

Subject: [PATCH v4 2/8] mac80211: ath9k: set default state for platform LEDs
Support default state for platform LEDs connected to ath9k device.
Now LEDs are correctly set on or off at ath9k module initialization.
Very useful if power LED is connected to wireless chip.
