ipq807x: add support for Linksys MX4200 V1 and V2

Linksys MX4200 is a 802.11ax Tri-band router/AP.
Specifications:
* CPU: Qualcomm IPQ8174 Quad core Cortex-A53 1.4GHz
* RAM: 512MB of DDR3
* Storage: 512Mb NAND
* Ethernet: 4x1G RJ45 ports (QCA8075)
* WLAN:
	* 2.4GHz: Qualcomm QCN5024 2x2 802.11b/g/n/ax 574 Mbps PHY rate
	* 5GHz: Qualcomm QCN5054 2x2@80MHz or 2x2@160MHz 802.11a/b/g/n/ac/ax 2402 PHY rate
	* 5GHz: Qualcomm QCN5054 4x4@80MHz or 2x2@160MHz 802.11a/b/g/n/ac/ax 2402 PHY rate
* LED-s:
	* RGB system led

* Buttons: 1x Soft reset 1x WPS
* Power: 12V DC Jack

Installation instructions:
Open Linksys Web UI - http://192.168.1.1/ca or http://10.65.1.1/ca depending on your setup.
Login with your admin password. The default password can be found on a sticker under the device.
To enter into the support mode, click on the “CA” link and the bottom of the page.
Open the “Connectivity” menu and upload the squash-factory image with the “Choose file” button.
Click start. Ignore all the prompts and warnings by click “yes” in all the popups.
The Wifi radios are turned off by default. To configure the router, you will need to connect your computer to the LAN port of the device.
Then you would need to write openwrt to the other partition for it to work
- First Check booted partition
fw_printenv -n boot_part

- Then install Openwrt to the other partition if booted in slot 1:
mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx4200v(X)-squashfs-factory.bin alt_kernel

- If in slot 2:
mtd -r -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx4200v(X)-squashfs-factory.bin kernel

Replace (X) with your model version either 1 or 2
