DMAEngine: add dmaengine_prep_interleaved_dma wrapper for interleaved api
commit b14dab792dee(DMAEngine: Define interleaved transfer request api) adds interleaved request api, this patch adds the dmaengine_prep_interleaved_dma just like we have dmaengine_prep_ for other modes to avoid drivers call: xxx_chan->device->device_prep_interleaved_dma().
