nodedev: Cleanup driver code and prototypes

Alter the node_device_driver source and prototypes to follow more
recent code style guidelines w/r/t spacing between functions, format
of the function, and the prototype definitions.

While the new names for nodeDeviceUpdateCaps, nodeDeviceUpdateDriverName,
and nodeDeviceGetTime don't follow exactly w/r/t a "vir" prefix, they
do follow other driver nomenclature style.
