drivers: sensor: ntc_thermistor: add support for generic NTC

Browse source 
Add support for a generic NTC, `ntc-thermistor-generic`. In this case,
the compensation table is provided via devicetree. Note that DT property
is prefixed with `zephyr,`, because while hardware related, it is linked
to a particular software implementation.
