hwmon: (lm92) Update documentation

Browse Source 
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.
