This add support for kernel 4.9 to the ar71xx target.
It was compile tested with the generic, NAND and mikrotik subtarget.
Multiple members of the community tested it on their boards and did not
report any major problem so far.
Especially the NAND part received some changes to adapt to the new
kernel APIs. The serial driver hack used for the Arduino Yun was not
ported because the kernel changed there a lot.

Remove the wget2nand script, drop the need for manual installation,
use sysupgrade instead.
There are now two different NAND images, one for 64 MiB flashes, the
other for >= 128 MiB
