ARM: SPEAr13xx: Pass generic DW DMAC platform data from DT
This replaces an earlier patch from Viresh Kumar to move the spear platform over to the generic DMA binding. This version is now based on the merged multiplatform capable spear platform, rather than the separate spear13xx/3xx/6xx directories.
