mac80211: split ath patch in dedicated subdir
The ath patch number is already large and adding other patch for ath11k will add more confusion with the patch numbering. Since the support of ath11k based device is imminent, prepare the mac80211 ath patch dir and split it in the dedicated ath5k, ath9k, ath10k and ath11k (empty for now).

+
+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.
