DT describes h/w. UIO is not a h/w block, so this does not belong in DT. 
A UIO vs. kernel driver is purely a kernel decision which shouldn't 
require a DT change.

The properties should be part of match data for a compatible string that 
needs them set. Or if they can be defined in a way that is actually a 
property of the h/w, then it would be acceptible. You'd still need to 
define compatible strings that the properties apply to.
