    boot-lantiq: Fix compilation with GCC 14
    
    This fixes the following compile problem:
    ```
    arv7506pw11.c: In function 'show_boot_progress':
    arv7506pw11.c:59:24: error: 'return' with a value, in function returning void [-Wreturn-mismatch]
       59 |                 return 0;
          |                        ^
    arv7506pw11.c:56:6: note: declared here
       56 | void show_boot_progress(int arg)
          |      ^~~~~~~~~~~~~~~~~~
    arv7506pw11.c:71:16: error: 'return' with a value, in function returning void [-Wreturn-mismatch]
       71 |         return 0;
          |                ^

       56 | void show_boot_progress(int arg)
          |      ^~~~~~~~~~~~~~~~~~
    ```
