firmware-utils: mktplinkfw: add support for TP-Link's new region codes
TP-Link has changed the way the region is stored in the firmware header, and now provides US- and EU-specific images for the Archer C7. Adding the new region codes is necessary to make LEDE/OpenWrt flashable on devices with the new stock firmwares again. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
