[yocto] Problem installing ath10k firmware

[Todd Efflam]

Finally was able to get it work - the error seemed to be a combination
of things.

We went with the modular build and ended up building the following as modules:
CONFIG_ATH10K=m
CONFIG_ATH10K_PCI=m
CONFIG_ATH_CARDS=m
CONFIG_ATH_COMMON=m

Then we added only "kernel-module-ath10k-pci" to IMAGE_INSTALL.   With
those two steps, we were then able to push the firmware to the
/lib/firmware/ directory as Fred had mentioned and ath10k was then
working with our card.  Thanks for the help!

Best,
Todd
