hwmon: (tmp102) Various fixes

Fixes from my driver review:
http://lists.lm-sensors.org/pipermail/lm-sensors/2010-March/028051.html

Only the small changes are in there, more important changes will come
later separately as time permits.

* Drop the remnants of the now gone detect function
* The TMP102 has no known compatible chip
* Include the right header files
* Clarify why byte swapping of register values is needed
* Strip resolution info bit from temperature register value
* Set cache lifetime to 1/3 second
* Don't arbitrarily reject limit values; clamp as needed
* Make limit writing unconditional
* Don't check for transaction types the driver doesn't use
* Properly check for error when setting configuration
* Report error on failed probe
* Make the driver load automatically where needed
* Various other minor fixes

 The Texas Instruments TMP102 implements one temperature sensor.  Limits can be
 set through the Overtemperature Shutdown register and Hysteresis register.  The
-sensor is accurate to 0.5 degrees over the range of -25 to +85 C, and to 1.0
-degrees from -40 to +125 C. Resolution of the sensor is 0.0625 degree.  The
+sensor is accurate to 0.5 degree over the range of -25 to +85 C, and to 1.0
+degree from -40 to +125 C. Resolution of the sensor is 0.0625 degree.  The
 operating temperature has a minimum of -55 C and a maximum of +150 C.
 
 The TMP102 has a programmable update rate that can select between 8, 4, 1, and
 0.5 Hz. (Currently the driver only supports the default of 4 Hz).
 
 The driver provides the common sysfs-interface for temperatures (see
-/Documentation/hwmon/sysfs-interface under Temperatures).
