This is a part of patchset where IBM's Flexible Service Interface is
introduced.
This commit models the FSI master. CFAM is hanging out of FSI master which is a bus controller.
The FSI master: A controller in the platform service processor (e.g.
BMC) driving CFAM engine accesses into the POWER chip. At the
hardware level FSI is a bit-based protocol supporting synchronous and
DMA-driven accesses of engines in a CFAM.
