ath79: add support for GL.iNet GL-X1200

This patch adds supports for GL-X1200.

Specification:
	- SOC: QCA9563 (775MHz)
	- Flash: 16 MiB
	- RAM: 128 MiB DDR2
	- Ethernet: 4x 1Gbps LAN + 1x 1Gbps WAN
	- Wireless: QCA9563(2.4GHz) and QCA9886(5GHz)
	- SIM: 2x SIM card slots
	- MicroSD: 1x microSD slot
	- Antenna: 2x external 5dBi antennas
	- USB: 1x USB 2.0 port
	- Button: 1x reset button
	- LED: 16x LEDs (3x GPIO controllable)
	- UART: 1x UART on PCB (JP1: 3.3V, RX, TX, GND)
	- OEM U-Boot supplies HTTP/GUI access

Implementation Notes
====================

Both the NOR and NAND variants boot off a NOR-based kernel,
consistent with the OEM's firmware.

The mode LEDs are
    * Boot, Running   system
    * Failsafe        2G
    * Upgrade         5G

Installation
============

Using sysupgrade
----------------

sysupgrade may be used to install a NAND image on a device running
a NAND image or a NOR image on a device running a NOR image. It is
recommended to *not* preserve config when upgrading from OEM firmware
or previous versions of OpenWrt. No supported sysupgrade path should
require "force". Transitioning from NOR to NAND can be accomplished

Using U-Boot
------------

The OEM U-Boot can be put into a graphical, firmware-upload mode by
holding down the button on the side of the router while applying power
and for a bit more than five seconds following with the current OEM
U-Boot. The power LED will come on, then the 5G LED will flash five
times, about once a second.  When the 5G LED stops flashing and the
2G LED lights solid, the router's U-Boot will provide an upload page
at http://192.168.1.1/ Either a browser may be used to upload an image,
or a utility such as curl may be used:

curl -X POST -F gl_firmware=\@*-nand-squashfs-factory.img \
         http://192.168.1.1/index.html
or
    curl -X POST -F gl_firmware=\@*-nor-squashfs-sysupgrade.bin \
         http://192.168.1.1/index.html

Note that NOR vs. NAND is based on the file name extension.
