In order to establish required properties based on the selected bus type, make the 'bus-type' property mandatory. Binary compatibility with existing DTB is kept as the driver does not enforce the property to be present, and shall fall-back to default parallel bus configuration, which was the only supported bus type, if the property is not specified.
