docs: arm: stm32: introduce STM32 DMA-MDMA chaining feature
STM32 DMA-MDMA chaining feature is available on STM32 SoCs which embed
STM32 DMAMUX, DMA and MDMA controllers. It is the case on STM32MP1 SoCs but
also on STM32H7 SoCs. But focus is on STM32MP1 SoCs, using DDR.
This documentation aims to explain how to use STM32 DMA-MDMA chaining
feature in drivers of STM32 peripheral having request lines on STM32 DMA.
