mac80211: install new firmware for ath9k-htc on target

For quite some time new firmware for ath9k-htc devices
is available in
http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/ath9k_htc/

Moreover ath9k-htc kernel driver expects this new v1.4
firmware to exist in /lib/firmware/ath9k_htc.

What happens currently:
