ARM: SAMSUNG: Remove Samsung specific enum type for dma direction
This patch removes the samsung specific enum type 's3c2410_dmasrc'
and uses 'dma_data_direction' instead.

ARM: SAMSUNG: Add common DMA operations
This patch adds common DMA operations which are used for Samsung DMA
drivers. Currently there are two types of DMA driver for Samsung SoCs.
The one is S3C-DMA for S3C SoCs and the other is PL330-DMA for S5P SoCs.
This patch provides funcion pointers for common DMA operations to DMA
client driver like SPI and Audio. It makes DMA client drivers support
multi-platform.
In addition, this common DMA operations implement the shared actions
that are needed for DMA client driver. For example shared actions are
filter() function for dma_request_channel() and parameter passing for
device_prep_slave_sg().

ARM: SAMSUNG: DMA Cleanup as per sparse
Function declaration differs between file: dma.c and file:dma.h
and SPARSE (Documentation/sparse.txt) gives error messages
All dma channels are members of 'enum dma_ch' and not 'unsigned int'
Please have a look at channel definitions in:
arch/arm/mach-s3c64xx/include/mach/dma.h
arch/arm/plat-samsung/include/plat/s3c-dma-pl330.h
arch/arm/mach-s3c2410/include/mach/dma.h
So all arguments should be of type 'enum dma_ch'

S3C: DMA: Change argument of s3c2410_dma_devconfig
All other functions have the channel argument of type 'unsigned int'
the s3c2410_dma_devconfig also accept the same value as argument but
treat it as type 'int'. Remove this anomaly by make it 'unsigned int'.
