    uboot-mediatek: fix build with swig 4.3.0
    
    Swig 4.3.0 has changed SWIG_Python_AppendOutput, which now requires an
    additional parameter `is_void`. SWIG_AppendOutput remains unchanged.
    This was fixed upstream in u-boot/u-boot at a63456b
    
    ```
    scripts/dtc/pylibfdt/libfdt_wrap.c: In function ‘_wrap_fdt_next_node’:
    scripts/dtc/pylibfdt/libfdt_wrap.c:5581:17: error: too few arguments to function ‘SWIG_Python_AppendOutput’
     5581 |     resultobj = SWIG_Python_AppendOutput(resultobj, val);
          |                 ^~~~~~~~~~~~~~~~~~~~~~~~
    ```
    
    This is the same fix as applied in 363e07d and 71b5de6.
    
    This commit is not part of the main branch, as the main branch has
    already bumped past 2025.01, removing the need for this patch.
    uboot-rockchip had the patch removed as part of 92814fe, which was the
    bump to 2025.01.

+Subject: [PATCH] scripts/dtc/pylibfdt/libfdt.i_shipped: Use SWIG_AppendOutput
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Swig has changed language specific AppendOutput functions. The helper
+macro SWIG_AppendOutput remains unchanged. Use that instead
+of SWIG_Python_AppendOutput, which would require an extra parameter
+since swig 4.3.0.
