iio:adc:mcp3911: Switch to generic firmware properties.
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.
