bmips: add support for TP-Link TD-W8968 V3

TP-Link TD-W8968 v3 is an 300Mbps Wireless N USB ADSL2+ Modem Router based on Broadcom BCM6318 SoC. Hardware: CPU: Broadcom BCM6318, 333 MHz, 1 core Flash: 8MB RAM: 64 MB Ethernet: 4x 10/100 Mbps Wireless: 802.11b/g/n, BCM43217 LEDs/Buttons: 10x / 3x USB: 1x 2.0 Flash instructions: * Assign static IP 192.168.1.100 to PC * Unplug the power source * Press the RESET button at the router, don't release it yet! * Plug the power source. Wait for some seconds * Release the RESET button * Browse to http://192.168.1.1 * Upload the openwrt-bmips-bcm6318-tp-link_td-w8968-v3-squashfs-cfe.bin file * Wait some minutes until the firmware upgrade finish.
