From: Tamizh chelvam <c_traja@xxxxxxxxxxxxxxxx>
This patch adds support to update btcoex priority value via nl80211.
Here driver will be exposing the supported frame format for this
feature via btcoex_support_flags which is a member of
wiphy structure. 10.4 based firmware support this feature.
WMI service WMI_SERVICE_BTCOEX is used to identify the firmware support
of this feature. BTCOEX needs to enable to modify this value.
This patch has dependency of
"cfg80211: Add new NL80211_CMD_SET_BTCOEX_PRIORITY to support BTCOEX"
patch.
