Commit mt76: drop default eeprom file for mt7986-firmware
(e3aa645b26) breaks eeprom loading for
Mercusys MR90X v1. As a result WiFi is not working at all.
This commit adds Mercusus MR90x to the caldata script (it works after the
commit mentioned above). And we can safely drop "81_fix_eeprom" script
as it's no longer required.

Installation
------------
1. Connect to the device using serial console.
2. Interrupt the Autoboot process when promted by sending '0' twice.
3. Serve the OpenWrt initramfs image using TFTP at 192.168.1.66. Name
the image "predator.bin" and conenct the TFTP server to the routers
LAN port.
4. Configure U-Boot to allow loading unsigned images from MMC
$ setenv bootcmd 'mmc read 0x40000000 0x00004400 0x0010000;
fdt addr $(fdtcontroladdr); fdt rm /signature; bootm 0x40000000';
saveenv
5. Transfer the image from U-Boot
$ setenv serverip 192.168.1.66; setenv ipaddr 192.168.1.1;
tftpboot 0x46000000 predator.bin; fdt addr $(fdtcontroladdr);
fdt rm /signature; bootm
6. Wait for OpenWrt to boot
7. Transfer the OpenWrt sysupgrade image to the router using scp.
8. Install OpenWrt using sysupgrade.

Installation
------------
1. Download the OpenWrt initramfs image. Copy the image to a TFTP server
reachable at 192.168.1.66/24. Rename the image to tufax4200.bin.
2. Connect the TFTP server to the AX4200. Conect to the serial console,
interrupt the autoboot process by pressing '4' when prompted.
3. Download & Boot the OpenWrt initramfs image.
$ setenv ipaddr 192.168.1.1
$ setenv serverip 192.168.1.66
$ tftpboot 0x46000000 tufax4200.bin
$ bootm 0x46000000
4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
using scp and install using sysupgrade.
$ sysupgrade -n <path-to-sysupgrade.bin>
Missing features
----------------
- The LAN port LEDs are driven by the switch but OpenWrt does not
correctly configure the output.
