Switch to generic device property accessors and make minor code
refactoring.

Make the clock optional since the driver is designed to operate without
explicit configuration in firmware thus making it useful on platforms
where clock is not or cannot be provided.

Changed in v2:

* Split the patch into two independent changes.
* Added struct device *dev at the top of probe() and remove() to re-use.
* Switched to device_set_node(...)
