stmhal/dma.c: Modify dma_init() to accept init struct as an argument
This removes hard-coded DMA init params from dma_init(), instead defining these parameters in a DMA_InitTypeDef struct that gets passed as an argument to dma_init() This makes dma_init more generic so it can be used for I2S and SD Card, which require different initialization parameters.
