From: Eliad Peller <eliad@xxxxxxxxxx>
Configure the QoS counters when entering D0i3.
The fw might use them later when performing protocol
offloading (we'll update the the counters back on
d0i3 exit in a following patch).
Non-QoS counter is handled internally in the fw, so
no need to configure it.
Also, add support for a new version of WOWLAN_CONFIG_CMD
