ar71xx: add support for TP-LINK TL-WR941ND v6 (international version)

The international version is completely different from the already
supported Chinese version. The WLAN of the QCA956x SoC used by this router
has been fixed in r46948.

This patch looks like it changes a lot in
700-MIPS-ath79-openwrt-machines.patch; that is not the case. Unfortunately,
quilt decided to completely reorganize the Kconfig patch even though only
a single section has been added.
