From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
This allows use of the driver with other types of firmware such as ACPI
PRP0001 based probing.
Also part of a general attempt to remove direct use of of_ specific
accessors from IIO.
Added an include for mod_devicetable.h whilst here to cover the
struct of_device_id definition.
