Subject: ath79: add support for Netgear WNDR3700v4

This patch adds ath79 support for Netgear WNDR3700v4.
Router was previously supported by ar71xx target only.
Note: device requires 'ar934x-nand' driver in kernel.

  * Flash: 128 MiB (NAND)
    - U-boot binary: 256 KiB
    - U-boot environment: 256 KiB
    - ART: 256 KiB
    - POT: 512 KiB
    - Language: 2 MiB
    - Config: 512 KiB
    - Traffic Meter: 3 MiB
    - Firmware: 25 MiB
    - ART Backup: 256 KiB
    - Reserved: 96 MiB
  * Ethernet: 5 x 10/100/1000 (4 x LAN, 1 x WAN) (AR8327)
  * Wireless:
    - 2.4 GHz b/g/n (internal)

  * UART: 4-pin connector JP1, 3.3V (Vcc, TX, RX, GND), 115200 8N1
  * Power supply: DC 12V 2.5A
  * MAC addresses: LAN=WLAN2G on case label, WAN +1, WLAN5G +2

Installation
============
  * TFTP recovery
  * TFTP via U-boot prompt
  * sysupgrade
  * Web interface

Note about partitioning: firmware partition offset (0x6c0000) is
hardcoded into vendor's u-boot, so this partition cannot be moved
and resized to include Netgear-specific flash areas (pot, language,
config, traffic_meter) not used by OpenWrt.
