This patchset adds ability to select any arbitrary target in a device tree.
A target is identified by it's name in the device tree (e.g. 'pib' for
processor, 'thread' for hardware thread).

Path based targets are specified using -P.

Examples:
    -P thread                    select all threads
    -P thread0                   select all threads with index 0
    -P pib0/thread               select all threads for proc 0
    -P pib0/core[1,2]/thread     select all threads for proc 0 and cores 1,2

The existing target selection using -p/-c/-t/-a/-l now maps to path based
targets.  Currently the only commands that are using path based targeting
are:

   probe
   getscom
   putscom
