Hauke Mehrtens 7bbf4117c6 ar71xx: Add kernel 4.9 support
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.

HACK: register the GPIO driver earlier to ensure that gpio_request calls
from mach files succeed.
