wl1271: Add proper WLAN-BT co-ex configuration, and enable co-ex.

Browse Source 
Add configuration values for the varous WLAN-BT co-ex configuration parameters,
and finally enable WLAN-BT co-ex. Based on preliminary measurements, it
appears the co-ex feature is not increasing WLAN power consumption, if BT
is not activated.
