[LEDE-DEV] [RFC 1/3] Update to latest ath10k-ct driver, enable AHB.

[greearb at candelatech.com]

From: Ben Greear <greearb at candelatech.com>

The driver updates include:

ath10k driver backport to fix WPA 'pn' related security bugs
(4.13 based driver only currently),
a fix for off-channel TX for CT wave-1 firmware, a likely
fix for napi related crashes, and a backport of the firmware fetch
patch.

AHB is needed for the IPQ4019 platform radios.

-Subject: [PATCH] ath10k: activate user space firmware loading again
-
-In commit 9f5bcfe93315 ("ath10k: silence firmware file probing
-warnings") the firmware loading was changed from request_firmware() to
-request_firmware_direct() to silence some warnings in case it fails.
-request_firmware_direct() directly searches in the file system only and
-does not send a hotplug event to user space in case it could not find
-the firmware directly.
-In LEDE we use a user space script to extract the calibration data from
-the flash memory which gets triggered by the hotplug event. This way the
-firmware gets extracted from some vendor specific partition when the
-driver requests this firmware. This mechanism does not work any more
-after this change.
