atmel-mci: change use of dma slave interface
Allow the use of another DMA controller driver in atmel-mci sd/mmc driver. This adds a generic dma_slave pointer to the mci platform structure where we can store DMA controller information. In atmel-mci we use information provided by this structure to initialize the driver (with new helper functions that are architecture dependant). This also adds at32/avr32 chip modifications to cope with this new access method.
