    ipq40xx: eap1300: add eap1300ext as alt model
    
    The EnGenius EAP1300 and EAP1300EXT use identical boards and firmware
    (as flashed) from the vendor.
    
    As with the EAP1300, the EAP1300EXT requires a specific firmware version
    to flash OpenWRT. Unfortunately, the required firmware is truncated on
    the vendor's website.
    
    A working file can be created as follows:
    
    ```
    curl \
    https://www.engeniustech.com/wp_firmware/eap1300-all-v3.5.3.5_c1.9.04.bin \
    | perl -pe 's/\x09EAP1300_A/\x0cEAP1300EXT_A/' \
    > eap1300ext-all-v3.5.3.5_c1.9.04.bin
    ```
    
    The file should have sha256:
    `58a1197a426139a12b03fd432334e677124cbe3384349bd7337f2ee71f1dcfd4`.
    
    Please see commit 2b4ac79 for further
    details.
    
    The vendor firmware must be decrypted before it can be flashed from
    OpenWRT. A tool able to do that is available from:
