of/device: Add input id to of_dma_configure()

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.
