    modify 500-ar9_vr9.patch from
    commit 29367aac42d6 ("lantiq: ltq-vmmc add support for ar9-vr9")
    
    - remove unused dependencies to external watchdog functions
      (wdog setup is already disabled)
    - using header file from kernel (asm/vpe.h) instead patched file (vpe.h)
    - cleanup whitspace warning
