qualcommax: ipq50xx: Add support for Zyxel SCR50AXE

This is tri-band WiFi6E capable router. Also Zyxel Nebula managed so no real local GUI. To open device 4 screws must be located uder the label.
Four latches are on front and two on each side. Better start from ethernet port side where 3 small latches are easy to handle.
FCC shows It's identical to WSQ65 sold as Zyxel Multy M6E but that's nowhare to be found yet. WSQ65 is not covered by this PR

Speficiations:
* SoC: Qualcomm IPQ5018
* RAM: 1GB DDR3
* Flash: Winbond W25N02KWZEIR 256MB
* UART: PCB "J3"  is located left from front LED strip
              (VCC/TX/RX/     /GND)   3.3V 115200n8
* Wi-Fi1: IPQ5018 (2x2 2.4 Ghz 802.11b/g/n/ax)
* Wi-Fi2: QCN6102 (2x2:2 5 Ghz 802.11an/ac/ax)
* Wi-Fi3: QCN6122 (2x2:2 6 Ghz 802.11an/ac/ax)
* Ethernet: QCA8337 4xLAN 1Gbit / 1xWAN 1Gbit
* Buttons: WPS , Reset
* LEDs: 13 in total
   RGB power, RGB wan, RGB status (cloud), RGB wifi, Green wps
* FCCID: I8803891

*Flash Instructions starts with getting root:
connect uart to J3 connector next to the front LEDs
go to failsafe when this shows up in log:
"Press the [f] key and hit [enter] to enter failsafe mode"
execute:
mount_root
passwd -d root
reboot

logon as root:
look for 'Please press Enter to activate this console.'
login is root password is empty
execute:
fw_setenv DebugFlag=0x1
fw_setenv bootdelay=0x2
passwd -d root
backup ubi partition "rootfs" into safe space
reboot

*OpenWrt installation
stop uboot and execute:
setenv ipaddr 192.168.1.1
setenv serverip 192.168.1.10
tftpboot *-factory.ubi
flash rootfs
reset

or:
tftpboot *-initramfs-uImage.itb
bootm
use sysupgrade as usual

*restore OEM from backup
stop uboot and execute:
setenv ipaddr 192.168.1.1
setenv serverip 192.168.1.10
tftpboot *-initramfs-uImage.itb
bootm
transfer rootfs.bin backup and execute:
ubiformat /dev/mtd16 -y -f /tmp/rootfs.bin
