This makes the wiphy and initial netdev registration the last step
in dev initialization. Apart from the fact that this looks right,
it can also be used to setup wiphy with the regulatory information
received from firmware after uploading the firmware. Also 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.

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

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

Rx buffers should be allocated for control and best effort endpoints only
after the enpoints connection is esablished. But this is done before the
endpoint connection is complete, we don't even the control and BE endpoints
that time. Move the buffer allocation after endpoint connection is over,
after ath6kl_init_hw_start(). Found in review, never seen any real issue
with this.

PS buffering of unicast Action frames that are sent in a context
of a BSS. In AP mode when the recepient station goes to powersave
and PS_POLL flag is not set, we would buffer the frames. Send out
unicast mgmt bufferred frame when PS_POLL is received.

This fixes a bug in P2P GO behavior when sending a GO Discoverability
Request to a client that is in sleep mode.

Using this patch, the user can bypass existing auto
suspend mode selection logic and force ath6kl to enter
into the suspend mode what he/she wants.

If the user doesn't choose any suspend mode while doing
insmod of the driver, auto suspend mode selection logic
will kick in and choose suspend mode based on the host
SDIO controller capability.

Generic module parameter is required to specify suspend
mode including Deep Sleep and WOW while doing insmod.
Renaming existing mod param variable suspend_cutpower
would be sufficient to meet this requirement.

New module parameter suspend_mode can take any one of
the below suspend state,
   1. cut power
   2. deep sleep
   3. wow

Testmode (TCMD and ART) was not enabled when fw-2.bin or fw-3.bin files
were available, fix that by fetching testmode file just after the
board file but before rest of the firmware files are fetched.

I also added testmode field to struct ath6kl and moved the module parameter
to core.c. Now all module parameters are grouped in one place.

Currently rx aggregation related states are maintained per
vif, but this will not properly work when operating in AP mode.
Aggregation is completely broken when more than one
11n stations are connected to AP mode vif. Fix this issue
by keeping station specific aggregation state in sta_list.

Now ath6kl is ready for splitting core code to ath6kl_core.ko module.
This also makes it possible to link both sdio and usb code to kernel
at the same time, which earlier failed miserably.

Currently core functions are spread between various files, group all
the functions into file and rename the functions to follow the style
used elsewhere in the driver. This will make it easier to a separate core
module.

Also fix a bug where wiphy is freed too early.
