Jonathan Cameron 6c6a6ee939 iio: ABI: temperature: Unify documentation for thermocouple fault detection. 
Kernel documentation for a given ABI element should not be duplicated
in multiple files, so pull them into one higher level documentation file.

What: /sys/bus/iio/devices/iio:deviceX/fault_ovuv KernelVersion: 5.1 Contact: linux-iio@vger.kernel.org Description: Overvoltage or Undervoltage Input Fault. The internal circuitry is protected from excessive voltages applied to the thermocouple cables. The device can also detect if such a condition occurs.

	Reading returns '1' if input voltage is negative or greater
	than VDD, otherwise '0'.

What: /sys/bus/iio/devices/iio:deviceX/fault_oc KernelVersion: 5.1 Contact: linux-iio@vger.kernel.org Description: Open-circuit fault. The detection of open-circuit faults, such as those caused by broken thermocouple wires. Reading returns '1' if fault, '0' otherwise.
