Add a devicetree binding to optionally force a different IIO channel
type.
This is useful in cases where ADC channels are connected to a circuit
that represent another unit such as a temperature or a current.
`channel-types` was chosen instead of `io-channel-types` as this is not
part of the iio consumer bindings.
