dmaengine: mmp_pdma: fix warning about slave caps
Fix the dmaengine complaint about missing slave caps : - declare the available bus widths - declare the available transfer types - declare the residue calculation type Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
