fdtdump: Change FDT_PROP prob handling to ease future addition

Browse source 
In order to ease future tags addition, perform operation related to
FDT_PROP when the tag is explicitly FDT_PROP instead of relying to a
kind of default value case.

Handle the FDT_PROP tag exactly in the same way as it is done for
other tags.

No functional modification.
