ipq40xx: Add ZTE MF289F

It's a 4G Cat.20 router used by Vodafone Italy (called Vodafone FWA)
and Vodafone DE\T-Mobile PL (called GigaCube).

Modem is a MiniPCIe-to-USB based on Snapdragon X24,
it supports 4CA aggregation.

There are currently two hardware revisions, which
differ on the 5Ghz radio:

AT1 = QCA9984 5Ghz Radio on PCI-E bus
AT2 = IPQ4019 5Ghz Radio inside IPQ4019 like 2.4Ghz

Installation
------------
1. Place OpenWrt initramfs image for the device on a TFTP
   in the server's root. This example uses Server IP: 192.168.0.2
2. Connect serial console (115200,8n1) to serial connector
   GND (which is right next to the thing with MF289F MIMO-V1.0), RX, TX
   (refer to this image: https://ibb.co/31Gngpr).
3. Connect TFTP server to RJ-45 port (WAN/LAN1).
4. Stop in u-Boot (using ESC button) and run u-Boot commands:

setenv serverip 192.168.0.2
setenv ipaddr 192.168.0.1
set fdt_high 0x85000000
tftp openwrt-ipq40xx-generic-zte_mf289f-initramfs-fit-zImage.itb
bootm $loadaddr

5. Please make backup of original partitions, if you think about revert to
   stock, specially mtd16 (Web UI) and mtd17 (rootFS).
Use /tmp as temporary storage and do:

WEB PARITION
--------------------------------------
cat /dev/mtd16 > /tmp/mtd16.bin
scp /tmp/mtd16.bin root@YOURSERVERIP:/
rm /tmp/mtd16.bin

ROOT PARITION
--------------------------------------
cat /dev/mtd17 > /tmp/mtd17.bin
scp /tmp/mtd17.bin root@YOURSERVERIP:/
rm /tmp/mtd17.bin

6. Login via ssh or serial and remove stock partitions
   (default IP 192.168.0.1):

 # this can return an error, if ubi was attached before
 # or rootfs part was erased before.
ubiattach -m 17

 # it could return error if rootfs part was erased before
ubirmvol /dev/ubi0 -N ubi_rootfs
 # some devices doesn't have it
ubirmvol /dev/ubi0 -N ubi_rootfs_data

7. download and install image via sysupgrade -n
 (either use wget/scp to copy the mf289f's squashfs-sysupgrade.bin
 to the device's /tmp directory)

 sysupgrade -n /tmp/openwrt-...-zte_mf289f-squashfs-sysupgrade.bin

Sometimes it could print ubi attach error, but please ignore it
if process goes forward.

Back to Stock (!!! need original dump taken from initramfs !!!)
-------------
1. Place mtd16.bin and mtd17.bin initramfs image
   for the device on a TFTP in the server's root.
   This example uses Server IP: 192.168.0.2
2. Connect serial console (115200,8n1) to serial console
   connector (refer to the pin-out from above).
3. Connect TFTP server to RJ-45 port (WAN/LAN1).
4. rename mtd16.bin to web.img and mtd17.bin to root_uImage_s
5. Stop in u-Boot (using ESC button) and run u-Boot commands:

This will erase RootFS+Web:
nand erase 0x1000000 0x800000
nand erase 0x1800000 0x1D00000

This will restore RootFS:
tftpboot 0x84000000 ${dir}root_uImage_s
nand erase 0x1800000 0x1D00000
nand write $fileaddr 0x1800000 $filesize

This will restore Web Interface:
tftpboot 0x84000000 ${dir}web.img
nand erase 0x1000000 0x800000
nand write $fileaddr 0x1000000 $filesize

After first boot on stock firwmare, do a factory reset.
Push reset button for 5 seconds so all parameters will
be reverted to the one printed on label on bottom of the router

(Warning: commit message did not conform to UTF-8 - hopefully fixed?,
added description of the pin-out if image goes down, reformatted
commit message to be hopefully somewhat readable on git-web,
redid some of the gpio-buttons & leds DT nodes, etc.)
