ath79: add support for GL.iNet GL-X300B

The GL-X300B is a industrial 4G LTE router based on the Qualcomm QCA9531 SoC. Specifications: - Qualcomm QCA9531 @ 650 MHz - 128 MB of RAM - 16 MB of SPI NOR FLASH - 2x 10/100 Mbps Ethernet - 2.4GHz 802.11b/g/n - 1x USB 2.0 (vbus driven by GPIO) - 4x LED, driven by GPIO - 1x button (reset) - 1x mini pci-e slot (vcc driven by GPIO) - RS-485 Serial Port (untested) Flash instructions: This firmware can be flashed using either sysupgrade from the GL.iNet firmware or the recovery console as follows: - Press and hold the reset button - Connect power to the router, wait five seconds - Manually configure 192.168.1.2/24 on your computer, connect to 192.168.1.1 - Upload the firmware image using the web interface RS-485 serial port is untested and may depend on the following commit in the GL.iNet repo: gl-inet@202e83a MAC addresses as verified by OEM firmware: vendor OpenWrt address WAN eth0 label LAN eth1 label + 1 2g phy0 label + 2 The label MAC address was found in the art partition at 0x0 Based on vendor commit: gl-inet@16c5708 Signed-off-by: John Marrett <johnf@zioncluster.ca>
