This patchset adds support for the STM32 MDMA controller.
The Master Direct memory access (MDMA) provides high-speed data transfer
between memory and memory or between peripherals and memory.
Contrary to STM32 DMA, the STM32 MDMA controller supports hardware LLI and
uses a larger integrated FIFO (128 vs 16 bytes)
