ath10k: make monitor vdev down before stoping it

Following sequence causes FW crash:
-monitor vdev up,
-monitor vdev stop,
-monitor vdev delete.
Making monitor vdev down before stoping it works ok:
-monitor vdev up,
-monitor vdev down,
-monitor vdev stop,
-monitor vdev delete.

ath10k: introduce dynamic WMI structures

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.

ath10k: split ath10k_wmi_service_ready_event_rx

Since the both firmwares we are going to support,
have significantly different APIs (WMI and shared
structures), it's easier to actually split the whole
event handling functions, instead cutting them inside.

The fork starts now on ath10k_wmi_process_rx().

ath10k: drop the fw versioning sanity check

It was corrupted and leading to compilation warning
core.c: In function 'ath10k_check_fw_version':
core.c:79: warning: comparison is always true due to limited range of data type

Since we are going to support new FW track in the driver,
the sanity check for fw version number would be an overkill
then. This is just for information purposes anyway.

ath10k: implement host memory chunks

10.X firmware can request a memory pool from host to offload
it's own resources. This is a feature designed especially
for AP mode where the target has to deal with large number
of peers.

So we allocate and map a consistent DMA memory which FW can
use to store e.g. peer rate contol maps.

ath10k: bring back the WMI path for mgmt frames

This is still the only way to submit mgmt frames in case
of 10.X firmware.

This patch introduces wmi_mgmt_tx queue, because of the
fact WMI command can block. This is a problem for
ath10k_tx_htt(), since it's called from atomic context.
The skb queue and worker are introduced to move the mgmt
frame handling out of .tx callback context and not block.

ath10k: implement firmware IE container support

Firmware IE containers can dynamically provide various information what
firmware supports. Also it can embed more than one image so updating firmware
is easy, user just needs to update one file in /lib/firmware/.

The firmware API 2 or higher will use the IE container format, the current API
1 will not use the new format but it still is supported for some time. FW API 2
files are named as firmware-2.bin (which contains both firmware and otp images)
and API 1 files are firmware.bin and otp.bin.

ath10k: extend the max_scan time

It was observed few times, the artificial max_scan limit we
are using mainly to detect FW hangs, can be not enough for
instance while being associated and during heavy traffic.

What we do if the FW won't return with scan results within
the max_time time is a scan abort.

This is especially visible with 10.X fw which in combination
with dual band HW (scanning 32 channels) can end up with
hw_scan close to 10 seconds.
