In previous method each AP settings flag is represented by a top-level flag attribute and conversion to enum cfg80211_ap_settings_flags had to be done before sending them to driver. This commit is to make it easier to define new AP settings flags and sending them to driver. This commit also deprecate sending of %NL80211_ATTR_EXTERNAL_AUTH_SUPPORT in %NL80211_CMD_START_AP. But to maintain backwards compatibility checks for %NL80211_ATTR_EXTERNAL_AUTH_SUPPORT in %NL80211_CMD_START_AP when %NL80211_ATTR_AP_SETTINGS_FLAGS not present in %NL80211_CMD_START_AP.
