Register wiphy after reading out chipid, so the chipid can be
used to determine chip features and not advertise WPA3/SAE
support to userspace on WILC3000. Note that wilc_netdev_cleanup()
will deregister the wiphy in fail path.

I think you did not address one of my comment in v5 about this change: in
wilc_cfg80211_init (wilc_create_wiphy's caller), there is still a
wiphy_unregister in the failure path, which does not make sense anymore since
this function does not register wiphy anymore.

Once fixed: with this patch iw phy shows correctly on my platform that wilc3000
does not support SAE authenticate command while wilc1000 does. And wilc1000
still works correctly, even with wpa3.
