    stmhal: L4: Adapt DMA to be able to support STM32L4 MCU series. · e64032d6

    The main thing is to change the DMA code in a way that the structure
    DMA_Stream_TypeDef (which is similar to DMA_Channel_TypeDef on stm32l4)
    is no longer used outside of dma.c, as this structure only exists for the
    F4 series.  Therefore I introduced a new structure (dma_descr_t) which
    handles all DMA specific stuff for configuration.  Further the periphery
    (spi, i2c, sdcard, dac) does not need to know the internals of the dma.
