wiphy: add driver quirk to disable SAE

Browse Source 
SAE/WPA3 is completely broken on brcmfmac, at least without a custom
kernel patch which isn't included in many OS distributions. In order
to help with this add a driver quirk so devices with brcmfmac can
utilize WPA2 instead of WPA3 and at least connect to networks at
this capacity until the fix is more widely distributed.
