hwmon: (ltc4245) Read only one GPIO pin
commit df16dd53c575d0cb9dbee20a3149927c862a9ff6 upstream.
Read only one of the GPIO pins as an analog voltage. The ADC can be
switched to a different GPIO pin at runtime, but this is not supported.
Previously, this driver would report the analog voltage of the currently
selected GPIO pin as all three GPIO voltages: in9_input, in10_input and
in11_input.
