"version 20 device" strongly suggests this is a hw2.1 device.
Currently there's only ath10k firmware for hw3.0 chips available. You
can look through ath10k mailing list for discussions on qca6174 hw2.1
(qca6164 is basically 1x1 instead of 2x2 from what I understand).

If not for the firmware confusion adding support to the driver is
probably as trivial as just adding the new pci device id to the
supported list.
