-also define a binding for fsl,eref-* properties

-v3
   -converted EREF specific properties to fsl,eref-*

+===================================================================
+Power Architecture CPU Binding
+Copyright 2013 Freescale Semiconductor Inc.
+
+Power Architecture CPUs in Freescale SOCs are represented in device trees as per the
+definition in ePAPR.
+
+In addition to the ePAPR definitions, the properties defined below may be present
+on CPU nodes.
+
+PROPERTIES
+
+   - fsl,eref-*
+        Usage: optional
+        Value type: <empty>
+        Definition: The EREF (EREF: A Programmer.s Reference Manual for Freescale Power Architecture)
+        defines the architecture for Freescale Power CPUs.  The EREF defines some architecture categories
+        not defined by the Power ISA.  For these EREF-specific categories, the existence of a property
+        named fsl,eref-[CAT], where [CAT] is the abbreviated category name with all uppercase letters
+        converted to lowercase, indicates that the category is supported by the implementation.
