[PATCH v3 06/12] hwmon (occ): Add command transport method for P8 and P9

From: "Edward A. James" For the P8 OCC, add the procedure to send a command to the OCC over I2C bus. This involves writing the OCC command registers with serial communication operations (SCOMs) interpreted by the I2C slave. For the P9 OCC, add a procedure to use the OCC
