staging: ath6kl: open/shared auth implementation
If the wpa_supplicant conf file supplies both open and shared
algorithm, and AP is configured as shared then connection never
happens. Since it is a FMAC driver additional logic is added in
driver which first detects this, then tries open algorithm for the
first time and when it fails tries the shared algo.
