Tomasz Bursztyka d99097177a wpa_supplicant: Enable Automatic Channel Selection support for AP mode 
Since hostapd supports ACS now, let's enable its support in
wpa_supplicant as well when starting AP mode.

Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>
[u.oelmann@pengutronix.de: rebased series from hostap_2_1~944 to master]
[u.oelmann@pengutronix.de: adjusted added text in defconfig]
