regulator: rn5t618: Convert to new style DT parsing 

Use the simplified DT parsing method to remove some duplicated
code.

Since this is a MFD subdevice and its device object doesn't have an
associated DT node, the configuration instance used to register the
regulators has been changed to point to the parent device.
