QCA6174 WLAN.RM.2.0 firmware uses max_tx_power instead of using max_reg_power
to set transmission power. The tx power was about -50dbm, after applying this
change, it become -32dbm.

ath.git patches for 4.7. Major changes:

ath10k

* implement set_tsf() for 10.2.4 branch
* remove rare MSI range support
* remove deprecated firmware API 1 support

ath9k

* add module parameter to invert LED polarity

wcn36xx

* fixes to get the driver properly working on Dragonboard 410c

In commit 97f95c93 ("iwlwifi: remove support for fw older than
-16.ucode") we accidentally changed the fw version reading code for
DVM devices.  The code intended to remove the old fw version API,
because all MVM firmwares version 16 and above that we support don't
use it anymore.  But DVM devices still use the old FW API.

Fix that by bringing the code back in.

Smatch complains about this code:

    error: we previously assumed '*ifp' could be null (see line 333)

The problem is that we recently changed these from "ifp" to "*ifp" but
there was one that we didn't update.

-       if (ret || !ifp || !ifp->ndev) {
+       if (ret || !(*ifp) || !(*ifp)->ndev) {
                if (ret != -ENODATA && ifp)

-                       ifp->stats.rx_errors++;
+                       (*ifp)->stats.rx_errors++;

I have updated it to *ifp as well.  We always call this function is a
non-NULL "ifp" pointer, btw.

USB8XXX_FW_MAX_RETRY is 3.  We were using a post-op loop
"while (retries--) {" but then the lines after that assume the loop
exits with retries set to zero.

I've fixed this by changing to a pre-op loop.  I started with retries
set to 4 instead of 3 so that we still go through the loop the same
number of times.
