操作

Merge ath-next from ath.git 

Major changes in ath10k:

* enable channel 144 on 5 GHz
* enable Adaptive Noise Immunity (ANI) by default
* add Wake on Wireless LAN (WOW) patterns support
* add basic Tunneled Direct Link Setup (TDLS) support
* add multi-channel support for QCA6174
* enable IBSS RSN support
* enable Bluetooth Coexistance whenever firmware supports it
* add more versatile way to set bitrates used by the firmware
