Fixes for the DMA transfer mode of the driver to try and improve the state of the code: - Ensure that dma_complete is set during the end of the command phase so that transfers do not stall awaiting the completion - Update the DMA debugging to provide a bit more useful information such as how many DMA descriptors where not processed and print the DMA addresses in hexadecimal. - Fix the DMA channel request code to actually request DMA for the S3CMCI block instead of whatever '0' signified. - Add fallback to PIO if we cannot get the DMA channel, as many of the devices with this block only have a limited number of DMA channels. - Only try and claim and free the DMA channel if we are trying to use it. This improves the driver DMA code to the point where it can now identify a card and read the partition table. However the DMA can still stall when trying to move data between the host and memory.
