Grab GPU sensor data from MRW
Grab GPU sensor data from MRW

Need to add GPU sensors to processor targets so they can be marked
present or called out by OCC/HTMGT.
(gpu_func_sensor, gpu_temp_sensor, and memory_temp_sensor)

Adding these sensors as a GPU# indexed array to each processor.
The array consists of IMPI_SENSOR_NAME, IPMI_SENSOR_ID for each sensor
+ a bitwise OBUS_CONFIG. OBUS_CONFIG is needed to tell if this GPU is
present or not for this particular backing board identified by
the OBUS_CONFIG.

Example bitwise OBUS_CONFIG
0x06 = 0b0110 -> OBUS_CONFIG Both 0x01 and 0x02 include this GPU
0x04 = 0b0100 -> OBUS_CONFIG Only 0x02 includes this GPU
