Unify DMA function signatures

[michprev]

Please notice different order of arguments in functions that use DMA. It would be nice to unify this I believe. For example (device_num, dmac_send_channel, dmac_receive_channel, send_buf, send_size, recv_buf, recv_size, other...).

It should be decided ASAP as any changes will break existing code.
