qualcommax: ipq50xx: Add support for Xiaomi AX6000
Add support for Xiaomi AX6000.

Speficiations:
* SoC: Qualcomm IPQ5018 (64-bit dual-core ARM Cortex-A53 @ 1.0Ghz)
* Memory: Etrontech EM6HE16EWAKG 512 MiB DDR3L-933
* Serial Port: 1v8 TTL 115200n8
* Wi-Fi: IPQ5018 (2x2 2.4 Ghz 802.11b/g/n/ax - up to 574 Mbps)
	 QCN9024 (4x4 5 Ghz 802.11an/ac/ax - up to 4804 Mbps)
 	 QCA9887 (1x1 5 Ghz 802.11ac/n - up to 433 Mbps)
* Ethernet: IPQ5018 integrated virtual switch connected to:
	- external QCA8337 switch   (3 LAN Ports 10/100/1000)
	- QCA8081 Phy WAN port  (10/100/1000/2500)
* Flash: Either of:
	- Gigadevice GD5F1GQ4RE9IGD (128 MiB)
	- ESMT F50D1G41LB (128 MiB)
* LEDs: 1x WLAN Link (GPIO 23 Active High)
	1x System Blue   (GPIO 24 Active High)
	1x System Yellow (GPIO 25 Active High)
	1x WAN Link Blue (GPIO 26 Active High)
	1x WAN Link Yellow   (GPIO 27 Active High)
	1x Green - Unused(GPIO 28 Active High)
	3x LAN Phy Green
	1x WAN Phy Green
* Buttons: 1x Reset  (GPIO 38 Active Low)

Known issue:
- QCA9887 doesn't come up (possibly due to 1-lane PCIe phy not coming up or missing method to drive power),
  hence the host PCIe controller is disabled in the DTS.

Flash instructions:

Download XMIR Patcher: https://github.com/openwrt-xiaomi/xmir-patcher

First flash a ubinized OpenWrt initramfs that will serve as the intermediate step, since
OpenWrt uses unified rootfs in order to fully utilize NAND and provide enough space for
packages, through either of the below two methods:

Installation via XMIR Patcher:

1. Load the initramfs image: openwrt-qualcommax-ipq50xx-xiaomi_ax6000-initramfs-factory.ubi

Installation via ubiformat method, through SSH:

1. If needed, enable SSH using XMIR Patcher.
2. Copy the file openwrt-qualcommax-ipq50xx-xiaomi_ax6000-initramfs-factory.ubi to the /tmp directory
3. Open an SSH shell to the router
4. Check which rootfs partition is your router booted in (0 = rootfs | 1 = rootfs_1):
nvram get flag_boot_rootfs
5. Find the rootfs and rootfs_1 mtd indexes respectively:
cat /proc/mtd
Please confirm if mtd18 and mtd19 are the correct indexes from above!
6. Use the command ubiformat to flash the opposite mtd with UBI image:
If nvram get flag_boot_rootfs returned 0:
ubiformat /dev/mtd19 -y -f /tmp/openwrt-qualcommax-ipq50xx-xiaomi_ax6000-initramfs-factory.ubi && nvram set flag_boot_rootfs=1 && nvram set flag_last_success=1 && nvram commit
otherwise:
ubiformat /dev/mtd18 -y -f /tmp/openwrt-qualcommax-ipq50xx-xiaomi_ax6000-initramfs-factory.ubi && nvram set flag_boot_rootfs=0 && nvram set flag_last_success=0 && nvram commit
7. Reboot the device by:
reboot

Continue in order to pernamently flash OpenWrt:
1. Upload the sysupgrade image to /tmp/ using SCP:
scp -O <path to image> root@192.168.1.1:/tmp/
2. Open an SSH shell to 192.168.1.1 from a PC within the same subnet
3. Use sysupgrade to flash the sysupgrade image:
sysupgrade -n -v /tmp/openwrt-qualcommax-ipq50xx-xiaomi_ax6000-squashfs-sysupgrade.bin

Device will reboot with OpenWrt, and then sysupgrade can be used to upgrade the device when desired.
