AA: ar71xx: reject TP-Link images containing a bootloader
Backport of r33944.
The original TP-Link firmware images can be flashed via
the sysupgrade command, however those may contain a
bootloader. Flashing such an image via sysupgrade
bricks the board, and it can't be recovered without
a serial console.
