    iio:adc:mcp3911: Switch to generic firmware properties.
    
    [ Upstream commit 4efc1c614d334883cce09c38aa3fe74d3fb0bbf0 ]
    
    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.
