There are some code which initializes various wiphy members
left outside ath6kl_cfg80211_init(), in ath6kl_core_init().
Move them into a single palce.

Move netdev->hw_features setting from ath6kl_core_init() to
init_netdev() so that it is done for every interface.

Split the wmi event processing into the one which needs to be
vif specific and the reset. This is a step towards avoiding
the need for wiphy and a netdev registration before getting
any message from firmware.

When the wmi event is vif specific, the validation of vif index
is taken care in ath6kl_wmi_proc_events_iface(). This also avoids
the need for a netdev to be registered while receiving initial events
like "target_ready" and "regulatory domain".

This makes the wiphy and initial netdev registration the last step
in dev initialization. Apart from the fact that this looks right,
it fixes a FIXME in ath6kl_core_init() where mac address is copied into
netdev->dev_addr, ath6kl_interface_add() takes care of this as well.

V2 - Remove reference to regulatory in commit log, even without
this patch regulatory information can be initialized.

Please rename this to ath6kl_wmi_proc_events_vif() or something similar.
Better to use term vif everywhere, it's not clear that iface here means vif.
Otherwise the patchset looks good to me.
