For now, use a module parameter (ath6kl_p2p) to allow P2P support
to be enabled. This is needed since there is no mechanism for
enabling the P2P mode more dynamically for a single netdev.

This cleans up the connect event parsing by defining a union in
struct wmi_connect_event to match with the three possible sets of
fields that the target uses depending on which type of connect
event is being indicated. In addition, two AP cases are now
separated from ath6kl_connect_event() so that correct field names
can be used to make it actually possible to understand what the
code is doing.

The bug hiding in the previous mess was in parsing the AID incorrectly
when processing the new station connecting event in AP mode. The fix
here for that is also fixing TIM updates for PS buffering to use the
correct AID.

Limit the length of the channel list to WMI_MAX_CHANNELS to avoid
rejection of the request in wmi.c. Since there is not really much
point in using a specific list of more than 32 channels, drop the
channel list if more channels are specified and scan all channels.

Fix cfg80211 scan API use: ar->scan_req must be set only if returning
success from scan() handler. The previous version would result in use
of freed memory and likely kernel panic should the scan request fail
to be sent to the target.

Just to make them a bit easier to read and unify naming. 32 suffix
in the function name means that it will be a 32 bit transfer. If there's
no number a buffer is transfered instead.

Use void pointers to get rid of ugly casts.

Don't provide target address as a pointer, pass it by value. Same for
the value used in write32().

Probe Request reporting will be needed for P2P and WPS, but some
firmware builds do not seem to like this when P2P is not enabled.
Since we do not yet enable P2P, the safest option here is to just
remove this call for now and bring it back as a more dynamic version
once ath6kl starts advertising support for P2P.
