dmaengine/dw_dmac: allow src/dst masters to be configured at runtime
Some platforms have flexible mastering capabilities and this needs to be selected at runtime. If the platform has specified private data in the form of the dw_dma_slave then fetch the source and destination masters from here. If this isn't present, default to the previous of 0 and 1. v2: cleanup whitespace Acked-by: Hans-Christian Egtvedt <hans-christian.egtvedt@atmel.com> Signed-off-by: Jamie Iles <jamie.iles@picochip.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
