Introduce LINUX-WCN driver type

Add a new driver type "LINUX-WCN" for Linux-based WCN chipset targets
for AP mode. It is needed to support driver specific operations while
sharing lot of the mac80211-based driver interface design. The WCN
driver type differs from this by being used with different configuration
tools on Android.
