STM32 DMA: replaced F4 header to match that for F2, and move header and source files to common.
In the header: - Fix DMA_SxCR_CT: change shift from 18 to 19 For use with the convenience functions: - Added DMA_SxCR_CHSEL generic values - Added DMA_STREAM - generic values - Added dma_if_offset - rather than separating out LISR and HISR - Added masks - Added dma_disable_double_buffer_mode()
