Devices sitting on proprietary busses have a device ID space that is owned by the respective bus and related firmware bindings. In order to let the generic OF layer handle the input translations to an IOMMU id, for such busses the current of_dma_configure() interface should be extended in order to allow the bus layer to provide the device input id parameter - that is retrieved/assigned in bus specific code and firmware. Augment of_dma_configure() to add an optional input_id parameter, leaving current functionality unchanged.
