[LEDE-DEV] [PATCH] ar71xx: Add TP-LINK TL-WR841N v12 support.

[Vittorio Gambaletta (VittGam)]

This router has the same hardware of TP-LINK TL-WR841N v11 (same
FCC ID, same TFTP image name...).

The stock firmware web interface does not seem to accept the LEDE
factory image, but it can be flashed via the u-boot TFTP recovery
by long-pressing the reset button after power on.

The TFTP image name is wr841nv11_tp_recovery.bin (yes, v11, not v12).
