The value for the multipoint dts property is ignored when parsing with of_property_read_bool, so we currently have multipoint always set as 1 even if value 0 is specified in the dts file.
Let's fix this to read the value too instead of just the property like the binding documentation says as otherwise MUSB will fail to work on devices with Mentor configuration that does not support multipoint.
