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