Subject: [PATCH v2 5/5] Documentation/devicetree/bindings: Add FSI device documentation

From: "Edward A. James" <eajames@...ibm.com>

Document the bindings for the SBE and OCC devices. SBE devices are
located on a CFAM on an FSI bus, and OCC devices are accessed through
the SBEFIFO.

Signed-off-by: Edward A. James <eajames@...ibm.com>
