Erik Skultety 87b31fe8a2 nodedev: driver: Create a generic mdevctl command translator 
Currently there are dedicated wrappers to construct mdevctl command.
These are mostly fine except for the one that translates both "start"
and "define" commands, only because mdevctl takes the same set of
arguments. Instead, keep the wrappers, but let them call a single
global translator that handles all the mdevctl command differences and
commonalities.
