[ARM] 4781/1: S3C24XX: DMA suspend and resume support
If an DMA channel was active at suspend, then ensure that it is correctly reconfigured when the system resumes. Note, the previous policy was for each driver to handle their own reconfiguration on resume. The policy has been changed to make the individual driver's job easier.
