[PATCH v2 07/10] drivers/hwmon/occ: Add error handling

From: "Edward A. James" Add logic to detect a number of error scenarios on the OCC. Export any errors through an additional non-hwmon device attribute. The error counting and state verification are required by the OCC hardware specification. Signed-off-by: Edward A. James
