[LEDE-DEV] [RFC] Support ath10k-ct out-of-tree driver.

[greearb at candelatech.com]

From: Ben Greear <greearb at candelatech.com>

This lets one use the ath10k-ct driver instead of the built-in
ath10k driver from the upstream kernel (or backports).

This has been lightly tested with ath10k-ct firmware on 9880
hardware.

*THIS PATCH BREAKS ath9k*  because I am compiling ath10k against
my own ath.ko, and so load my own ath.ko.  I am not sure the
best way to fix this:  Compile my own ath* modules to replace
upstream, or fix just my ath10k sub-dir to build on it's own
and link against standard ath module....
