A new dma request id 'DMACH_DT_PROP' is introduced for client drivers requesting a dma channel. This request indicates that a device tree node property represting the dma channel is available in 'struct samsung_dma_info'. The dma channel request wrapper uses the node property value as the value for the filter parameter.
