iio: add child nodes support in iio backend framework
Add an API to support IIO generic channels binding:
http://devicetree.org/schemas/iio/adc/adc.yaml#
This new API is needed, as generic channel DT node isn't populated as a
device.
Add devm_iio_backend_fwnode_get() to allow an IIO device backend
consumer to reference backend phandles in its child nodes.
