[LEDE-DEV,1/4] Update to latest ath10k-ct driver, enable AHB.

From: Ben Greear <greearb@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.

Please keep KERNEL_RELAY out of the dependencies, we want CONFIG_RELAY
disabled in our default kernels. See the following commit:

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=e9fa0b9f3ae0711dd07d61b482f6bdb6446b4f9c
