dmaengine: shdma: convert to platform device resources
The shdma dmaengine driver currently uses numerous macros to support various platforms, selected by ifdef's. Convert it to use platform device resources and lists of channel descriptors to specify register locations, interrupt numbers and other system-specific configuration variants. Unavoidably, we have to simultaneously convert all shdma users to provide those resources. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
