    Adjust function definition in drm_fb_helper.c to avoid clang 15 warning
    
    With clang 15, the following -Werror warning is produced:
    
        sys/dev/drm2/drm_fb_helper.c:86:18: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
        framebuffer_alloc()
                         ^
                          void
    
    This is because framebuffer_alloc() is declared with a (void) argument
    list, but defined with an empty argument list. Make the definition match
    the declaration.
    
    MFC after:      3 days
    
    (cherry picked from commit 7a7bbe10216e0fbcf3af7a122d249cb000d517c7)
