fsi: Add regmap and refactor sbefifo
Merge series from Eddie James <eajames@linux.ibm.com>: The SBEFIFO hardware can now be attached over a new I2C endpoint interface called the I2C Responder (I2CR). In order to use the existing SBEFIFO driver, add a regmap driver for the FSI bus and an endpoint driver for the I2CR. Then, refactor the SBEFIFO and OCC drivers to clean up and use the new regmap driver or the I2CR interface. This branch just has the regmap change so it can be shared with the FSI code.
