ath10k: add testmode
Add testmode interface for starting and using UTF firmware which is used to run
factory tests. This is implemented by adding new state ATH10K_STATE_UTF and user
space can enable this state with ATH10K_TM_CMD_UTF_START command. To go back to
normal mode user space can send ATH10K_TM_CMD_UTF_STOP.

ath: Remove extern from function prototypes
There are a mix of function prototypes with and without extern
in the kernel sources. Standardize on not using extern for
function prototypes.
Function prototypes don't need to be written with extern.
extern is assumed by the compiler. Its use is as unnecessary as
using auto to declare automatic/local variables in a block.

ath10k: mac80211 driver for Qualcomm Atheros 802.11ac CQA98xx devices
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:
