hwmon: Driver for TI TMP103 temperature sensor

Driver for the TI TMP103.

The TI TMP103 is similar to the TMP102.  It differs from the TMP102
by having only 8 bit registers.

+Kernel driver tmp103
+====================
+
+Supported chips:
+  * Texas Instruments TMP103
+    Prefix: 'tmp103'
+    Addresses scanned: none

+Description
+-----------
+
+The TMP103 is a digital output temperature sensor in a four-ball
+wafer chip-scale package (WCSP). The TMP103 is capable of reading
+temperatures to a resolution of 1°C. The TMP103 is specified for
+operation over a temperature range of –40°C to +125°C.
+
+Resolution: 8 Bits
+Accuracy: ±1°C Typ (–10°C to +100°C)
+
+The driver provides the common sysfs-interface for temperatures (see
+Documentation/hwmon/sysfs-interface under Temperatures).
+
+Please refer how to instantiate this driver:
