hw/fsi: Introduce IBM's fsi-slave model

Browse source 
This is a part of patchset where IBM's Flexible Service Interface is
introduced.

The FSI slave: The slave is the terminal point of the FSI bus for
FSI symbols addressed to it. Slaves can be cascaded off of one
another. The slave's configuration registers appear in address space
of the CFAM to which it is attached.
