This patchset adds support for the STM32 DMA controller.
This controller provides 8 channels dedicated to managing memory access
request from one or more peripherals.
Each stream can have up to 8 requests in total.

Changes since v1:
- remove dmamux boolean as it is not needed
- replace dma by DMA in Kconfig
- add default return value in stm32_dma_get_width()
- add defalut return value in stm32_dma_get_burst()
- use lower case for constant hexadecimal values
