Core device tree changes for Linux v3.4

Browse source 
This branch contains a minor documentation addition, a utility
 function for parsing string properties needed by some of the new ARM
 platforms, disables dynamic DT code that isn't used anywhere but on a
 few PPC machines, and exports DT node compatible data to userspace via
 UEVENT properties.  Nothing earth shattering here.
