This adds a new driver to support the s3c24xx dma using the dmaengine and makes the old one in mach-s3c24xx obsolete in the long run. Conceptually the s3c24xx-dma feels like a distant relative of the pl08x with numerous virtual channels being mapped to a lot less physical ones. The driver therefore borrows a lot from the amba-pl08x driver in this regard. Functionality-wise the driver gains a memcpy ability in addition to the slave_sg one. The driver supports both the method for requesting the peripheral used by SoCs before the S3C2443 and the different method for S3C2443 and later. On earlier SoCs the hardware channels usable for specific peripherals is constrainted while on later SoCs all channels can be used for any peripheral. Tested on a s3c2416-based board, memcpy using the dmatest module and slave_sg partially using the spi-s3c64xx driver.
