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().
