Some MT7915 calibration data consists of two parts. The first part
"eeprom" size is 0xe00. The second part "precal" size is 0x19c10.
Though some devices may not have precal data, it's better to assume
that precal data exists as no users/developers confirm it. On the
other hand, some devices definitely do not contain precal data
because the EEPROM partition size is smaller than the precal NVMEM
cell size.

Some MT7915 devices need to load the second part of the eeprom to
work properly. The mt76 driver is not yet ready to read the pre-cal
data via the NVMEM cell. Therefore, partially revert commit to fix
the device probe issue on some devices.
P.S.
Except for D-Link and Ubnt devices, It is still uncertain whether
pre-cal data is required for other devices in the patch.
This partially reverts commit 9ac891f8c4.

These devices do not use rgmii2 as gpio, therefore remove rgmii2 pin group
from state-default. Remove overwriting the ethernet node for these devices.
Move claiming the rgmii2 group from mt7621_zyxel_nwa-ax.dtsi to
mt7621_zyxel_nwa50ax.dts as it's only the latter using rgmii2 pins as gpio.
Remove duplicate ethernet overwrite from mt7621_tplink_archer-x6-v3.dtsi.
Claim rgmii2 group as gpio on mt7621_bolt_arion.dts as it uses an rgmii2
pin, 26, as gpio.

Hardware
--------
CPU: Mediatek MT7621
RAM: 256M DDR3
FLASH: 128M NAND
ETH: 1x Gigabit Ethernet
WiFi: Mediatek MT7915 (2.4/5GHz 802.11ax 2x2 DBDC)
BTN: 1x Reset (NWA50AX only)
LED: 1x Multi-Color (NWA50AX only)
UART Console
------------
NWA50AX:
Available below the rubber cover next to the ethernet port.
NWA55AXE:
Available on the board when disassembling the device.
Settings: 115200 8N1
Layout:
<12V> <LAN> GND-RX-TX-VCC
Logic-Level is 3V3. Don't connect VCC to your UART adapter!
Installation Web-UI
-------------------
Upload the Factory image using the devices Web-Interface.
As the device uses a dual-image partition layout, OpenWrt can only
installed on Slot A. This requires the current active image prior
flashing the device to be on Slot B.
If the currently installed image is started from Slot A, the device will
flash OpenWrt to Slot B. OpenWrt will panic upon first boot in this case
and the device will return to the ZyXEL firmware upon next boot.
If this happens, first install a ZyXEL firmware upgrade of any version
and install OpenWrt after that.
Installation TFTP
-----------------
This installation routine is especially useful in case
* unknown device password (NWA55AXE lacks reset button)
* bricked device
Attach to the UART console header of the device. Interrupt the boot
procedure by pressing Enter.
The bootloader has a reduced command-set available from CLI, but more
commands can be executed by abusing the atns command.
Boot a OpenWrt initramfs image available on a TFTP server at
192.168.1.66. Rename the image to owrt.bin
$ atnf owrt.bin
$ atna 192.168.1.88
$ atns "192.168.1.66; tftpboot; bootm"
Upon booting, set the booted image to the correct slot:
$ zyxel-bootconfig /dev/mtd10 get-status
$ zyxel-bootconfig /dev/mtd10 set-image-status 0 valid
$ zyxel-bootconfig /dev/mtd10 set-active-image 0
Copy the OpenWrt ramboot-factory image to the device using scp.
Write the factory image to NAND and reboot the device.
$ mtd write ramboot-factory.bin firmware
$ reboot
