Introduce the cmd and events definitions for 10.X FW API
and make up the wmi_10x_cmd_map. This is the core of
host-firmware WMI interface for 10.X FW branch.

This is the initial framework to implement dynamic
WMI API in order to support new firmware (from so
called 10.X branch)
The realization is to have a static WMI cmd map for
each of the firmwares, registered upom wmi init.
This patch creates such map for MAIN FW, updates
wmi_cmd_send() calls to take as a parameter
the map value instead of direct WMI enum.
As soon as complete 10.X API will be on place,
we will introduce the FW IE mechanics to dynamicaly
identify which FW is being used and based on that
we will use correct map, API, structures, etc.

It's not really necessary to have this processed
in a worker. There are no sleepable calls (and
actually shouldn't be).

It is no longer used nor necessary since WMI

The patch prevents beacon misses in some case of
heavy load on a system.
If a beacon can't be transmitted directly from an
SWBA event it will be left in arvif->beacon and
transmission will be retried once TX credits
become available.

The patch removes HTC endpoint tx workers in
favour of direct command submission. This makes a
lot more sense for data path.
mac80211 queues are effectively stopped/woken up
in a more timely fashion preventing build up of
frames. It's possible to push more traffic than
the device/system is able to handle and have no
hiccups or performance degradation with UDP
traffic.
WMI commands will now report errors properly and
possibly block as they actively can wait for tx
credits to become available.

This will be necessary for further changes in
command submission scheme.
Once HTC is cleaned up WMI commands will finally
block.
This requires for SWBA to be processed in a
non-atomic context for now. Once other necessary
changes are in this will be reverted.

The mgmt_rx event structure has been expanded.
Since the structure header is expanded the payload
(i.e. mgmt frame) is shifted by a few bytes. This
needs to be taken into account in order to support
both old and new firmware.
This introduces a fw_features to keep track of any
FW-related ABI/behaviour changes.

This implements a limited subset of what can be
reported in the survey dump.
This can be used for assessing approximate channel
load, e.g. for automatic channel selection.

Until now ath10k assumed 3 spatial streams.
However some devices support only 2 spatial
streams.
This patch improves performance on devices that
don't support 3 spatial streams.

Restart the hardware if FW crashes.
If FW crashes during recovery we leave the
hardware in a "wedged" state to avoid recursive
recoveries.
When in "wedged" state userspace may bring
interfaces down (to issue stop()) and then bring
one interface (to issue start()) to reload
hardware manually.

Here's a new mac80211 driver for Qualcomm Atheros 802.11ac QCA98xx devices.
A major difference from ath9k is that there's now a firmware and
that's why we had to implement a new driver.
The wiki page for the driver is:
http://wireless.kernel.org/en/users/Drivers/ath10k
The driver has had many authors, they are listed here alphabetically:
