Since Linux 4.6, mtd->priv no longer points to the NAND specific
structure. Under 4.9 it contains NULL, thus using it to access
the fields of the nand_chip structure causes an invalid pointer
dereference.
Update the code to use the mtd_to_nand() helper under 4.9 to obtain
the address of the chip specific data.
Compile tested only.

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.

This patch adds support for the Airtight C-60.
SOC: Atheros AR9344 rev 2 (CPU:560.000MHz)
RAM: 128 MiB
NOR: MX25L3205D 4MiB
NAND: ST Micro NAND 32MiB 3,3V 8-bit
SW-NET: AR8327N (2 Ports)
WLAN1: Dual-Band AR9340 Rev:2 (built-in SoC)
WLAN2: Dual-Band AR9300 Rev:4 PCIe Chip
The switch is setup for an accesspoint:
LAN1: (gigabit) is the wan-port.
LAN2: (fast ethernet) is bridged with the br-lan.
Flashing Guide (via initramfs):
1. Connect a PC to the serial port of the C-60.
power up the C-60.
Enter u-boot command prompt:
#> nand erase
#> setenv bootcmd "bootm 0x9f060000"
#> saveenv
#> setenv ipaddr 192.168.1.1
#> setenv netmask 255.255.255.0
#> setenv serverip 192.168.1.100
#> setenv bootfile lede-ar71xx-nand-c-60-initramfs-kernel.bin
#> tftpboot
#> bootm
2. Wait for the C-60 to boot LEDE.
On the root prompt. Enter:
# ubiformat /dev/mtd4
# ubiattach -p /dev/mtd4
3. After that copy the sysupgrade.tar onto the router and run:
# sysupgrade sysupgrade.tar
to flash the image.
Special thanks to Chris Blake <chrisrblake93@gmail.com>. He provided
a C-60 unit and he helped with debugging the switch, LEDs and platfrom
support.
