powerpc/fsl: Added binding for Freescale CoreNet coherency fabric (CCF)
The CoreNet coherency fabric is a fabric-oriented, conectivity infrastructure that enables the implementation of coherent, multicore systems. The CCF acts as a central interconnect for cores, platform-level caches, memory subsystem, peripheral devices and I/O host bridges in the system.

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.

+ Value type: <u32>
+ Definition: The Coherency Subdomain ID Port Mapping Registers and
+ Snoop ID Port Mapping registers, which are part of the CoreNet
+ Coherency fabric (CCF), provide a CoreNet Coherency Subdomain
+ ID/CoreNet Snoop ID to cpu mapping functions. Certain bits from
+ these registers should be set if the coresponding CPU should be
+ snooped. This property defines a bitmask which selects the bit
+ that should be set if this cpu should be snooped.
