spi: dw: Discard static DW DMA slave structures
Having them declared is redundant since each struct dw_dma_chan has
the same structure embedded and the structure from the passed dma_chan
private pointer will be copied there as a result of the next calls
chain:
dma_request_channel() -> find_candidate() -> dma_chan_get() ->
device_alloc_chan_resources() = dwc_alloc_chan_resources() ->
dw_dma_filter().
So just remove the static dw_dma_chan structures and use a locally
declared data instance with dst_id/src_id set to the same values as
the static copies used to have.
