mpt2sas, mpt3sas: log exceeded temperature thresholds
This patch will log a message when driver receives "Temperature Threshold
exceeded" event from any temperature sensor.
The message will look similar to like:
mpt3sas0: Temperature Threshold flags a b c d exceeded for Sensor: x !!!
mpt3sas0: Current Temp In Celsius: y
where a b c d are threshold flags 0 1 2 3
Change_set:
1. Get the number of sensor count of this IOC by reading IO Unit page 8 at
driver initialization time.
2. Also unmask the Temperature Threshold Event at driver initialization
time
3. Whenever a MPI2_EVENT_TEMP_THRESHOLD event is received from the
firmware, then print the sensor number, the maximum threshold number it
has exceed and the current temperature of this sensor.
