of: Add function for generating a DT modalias with a newline
The modalias sysfs attr is lacking a newline for DT aliases on platform devices. The macio and ibmebus correctly add the newline, but open code it. Introduce a new function, of_device_modalias(), that fills the buffer with the modalias including the newline and update users of the old of_device_get_modalias function.
