ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devices

Browse Source 
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:

Bartosz Markowski <bartosz.markowski@tieto.com>
Janusz Dziedzic <janusz.dziedzic@tieto.com>
Kalle Valo <kvalo@qca.qualcomm.com>
Marek Kwaczynski <marek.kwaczynski@tieto.com>
Marek Puzyniak <marek.puzyniak@tieto.com>
Michal Kazior <michal.kazior@tieto.com>
Sujith Manoharan <c_manoha@qca.qualcomm.com>

/*
* Bootloader Messaging Interface (BMI)
*
* BMI is a very simple messaging interface used during initialization
* to read memory, write memory, execute code, and to define an
* application entry PC.
*
* It is used to download an application to QCA988x, to provide
* patches to code that is already resident on QCA988x, and generally
* to examine and modify state. The Host has an opportunity to use
* BMI only once during bootup. Once the Host issues a BMI_DONE
* command, this opportunity ends.
*
* The Host writes BMI requests to mailbox0, and reads BMI responses
* from mailbox0. BMI requests all begin with a command
* (see below for specific commands), and are followed by
* command-specific data.
*
* Flow control:
* The Host can only issue a command once the Target gives it a
* "BMI Command Credit", using AR8K Counter #4. As soon as the
* Target has completed a command, it issues another BMI Command
* Credit (so the Host can issue the next command).
*
* BMI handles all required Target-side cache flushing.
