[PATCH v4 08/13] dt-bindings: iio: temperature: ltc2983: change default excitation for custom thermistors

[Cosmin Tanislav]

From: Cosmin Tanislav <cosmin.tanislav@xxxxxxxxxx>

Excitation cannot be set to auto-range when using a custom thermistor
or Steinhart sensor type. Default it to 1000nA to match the driver
and remove the auto-range value from the enum.
