temperature_sensors: Deprecate "NTC 100K beta 3950" thermistor
It seems the common "beta 3950" thermistors generally follow a
temperature table defined by the new "Generic 3950" definition. Using
a table that actually follows the "beta 3950" temperature curve is
generally less accurate. Deprecate the existing "NTC 100K beta 3950"
definition to avoid this common issue.
