Hi John,

the watchdog driver should just be the driver that includes
reset functions called from driver and then send reset signal
to abnormal hw.. 

however luckily ETHDMA_RST provided from watchdog is not required
and even actually the latest driver didn't refer to the property
no longer. So i will remove it from dtsi in the next version 

  Sean
