hostapd: Disable WPS 2.0 when WPA-TKIP only configuration is set

Browse Source 
WSC 2.0 deprecates use of WPA (TKIP) and does not allow WPA/TKIP only
configuration (i.e., WPA2/CCMP needs to be enabled in mixed mode for
WPA/TKIP to be acceptable). Enforce this by disabling WPS if
configuration enables WPA/TKIP without WPA2/CCMP.
