This patch series adds a driver to communicate with the POWER processor
On-Chip Controller (OCC), from a service processor. Communication is performed
via the SBEFIFO driver, which required a new in-kernel API.

An application to test the OCC driver can be found at

Changes since v3:
 * Add include file for occ driver.

Changes since v2:
 * Switch to use getSRAM/putSRAM over the SBE. This is significantly more
efficient and also circumvents the need to set up OCB channels manually.
 * Include the in-kernel API (for hwmon driver).
 * xfr struct embedded in client
 * add sequence number and checksum to command
