linux-firmware: Add missing firmware for the carl9170 driver.

For a long time now Atheros USB AR9170 devices have been using the carl9170 driver which relies on the carl9170-1.fw firmware file. This firmware is built by current buildroot, but its output is not copied to the resulting rootfs. This patch fixes that.

Please backport to 2017.02.x branch.

Hello,

Firmware files are not "built by Buildroot", since they are only provided as binary-only files. Buildroot merely installs them, so I've fixed up the commit log before applying.

So you're using the LTS branch for some projects?

Peter: as requested by Karoly, I think we can backport this patch into the LTS branch.

Thanks!

Hello,

Ahh you're right, thank you.

Yes, at least that's what we're working on. Up until now we've used Debian as our base system, but because we'd like to push out software updates over mobile data, we're making a new firmware that is built by buildroot to keep our image small. We're targeting said branch (2017.02.x), but not because it is 'LTS', but because it seems to be the latest released (and/or stable) branch that is not a moving target like master.

Thank you,
Karoly
