None of these vf610-zii boards have a battery or super-capacitor
holding up power to the SNVS RTC embedded in the Vybrid SoC,
so it is preferable to disable the snvsrtc node.

On vf610-zii-ssmb-spu3 board there is a supervisory microcontroller that
provides the watchdog functionality, so disable the on-chip Vybrid's
watchdog.
