Update datasheet references. Replace misleading 'force parameter needed'
with 'must be instantiated explicitly'. Explain the reason for the missing
auto-detection. Mention all supported chips in Kconfig.

Description
-----------
-This driver implements support for the National Semiconductor LM92
-temperature sensor.
+This driver implements support for the National Semiconductor / Texas
+Instruments LM92 temperature sensor.
Each LM92 temperature sensor supports a single temperature sensor. There are
alarms for high, low, and critical thresholds. There's also an hysteresis to
control the thresholds for resetting alarms.
-Support was added later for the LM76 and Maxim MAX6633/MAX6634/MAX6635,
-which are mostly compatible. They have not all been tested, so you
-may need to use the force parameter.
+The driver also supports LM76 and Maxim MAX6633/MAX6634/MAX6635, which are
+mostly compatible but do not have a vendor ID register and therefore must be
+instantiated explicitly.

If you say yes here you get support for National Semiconductor LM92
- and Maxim MAX6635 sensor chips.
+ and LM76 as well as Maxim MAX6633/6634/6635 sensor chips.
This driver can also be built as a module. If so, the module
will be called lm92.
