[LEDE-DEV] [PATCH v4] Support Candela-Tech ath10k out-of-tree driver.

[greearb at candelatech.com]

From: Ben Greear <greearb at candelatech.com>

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

This should be a drop-in replacement, as well as enabling
better CT firmware support.
