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).
