ath79: add support for Netgear WNDR4300

This patch adds ath79 support for Netgear WNDR4300.
Router was previously supported by ar71xx target only.
Note: device requires 'ar934x-nand' driver in kernel.

Specification
=============
  * Description: Netgear WNDR4300
  * Loader: U-boot
  * SOC: Atheros AR9344 (560 MHz)
  * RAM: 128 MiB
  * 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)
	- 5 GHz a/n (AR9580)
  * USB: yes, 1 x USB 2.0
  * Buttons:
	- Reset
	- WiFi (rfkill)
	- WPS
  * LEDs:
	- Power (amber/green)
	- WAN (amber/green)
	- WLAN 2G (green)
	- WLAN 5G (blue)
	- 4 x LAN (amber/green)
	- USB (green)
	- WPS (amber/green)
  * 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.
