android: enable wifi ap mode

因為這版bsp，wifi 可以動。所以看看是不是 ap mode 也可以起得來。
直接 enable thethering -- portable Wi-Fi hotspot。
結果是 Error。

log 是..

所以問題應該是在： E/SoftapController( 2309): AR6000_IOCTL wlap0 set wlan state failed: -1:No such device
然後記得以前 auron 說過，當初 ap mode fail 是 interface name 不對。
對照一下，果然，前面 wlan_tool 使用 softap0，後面 framework 都用 wlap0。

所以修改一下 wlan_tool
... 這個是在 atheros wifi sdk 的 driver project 中..

附記：auron 改 WifiService.java ，其中 SOFTAP_IFACE=" " 她改 wlan1
要注意 可以作為 tether 的 interface 寫在 framework/base/core/res/res/values/config.xml:
