bmips: bcm6328: add Innacomm W3400V6

Innacomm W3400V6 is an xDSL B/G wireless router based on Broadcom
BCM6328 SoC.

SoC: Broadcom BCM6328
CPU: BMIPS4350 V8.0, 320 MHz, 1 core
Flash: SPI-NOR 8MB, MX25L6406E
RAM: 64 MB
Ethernet: 4x 10/100 Mbps
Switch: Integrated
Wireless: 802.11b/g, BCM4312
LEDs/Buttons: 9x / 2x

Flash instruction, web UI:
1. Set a static IP on your computer compatible with 192.168.1.1, i.e
192.168.1.100.
2. Connect the ethernet cable from your computer to the router.
3. Make sure the router is powered off.
4. Press the reset button, don't release it yet!
5. While pressing reset, power on the router.
6. Wait 10 seconds or more.
Note: The power LED is red at first then turns to solid green when
ready.
7. Release the reset button.
8. Browse to 192.168.1.1
9. Select .bin file.
10. Upgrade the image.
11. Wait for it to reboot.
