This patch adds all required platform-specific data and initialization code to support the generic amba-pl08x driver on S3C64xx SoCs. Also some compatibility definitions are added to make the transition from legacy API to DMA engine easier. The biggest hack here is passing const char * pointers through DMA resource, casted to unsigned long, but this is how Samsung DMA wrappers (used to support both s3c-dma and DMA engine in drivers) are designed.
