dmaengine: stm32-dma: add support to trigger STM32 MDMA
STM32 MDMA can be triggered by STM32 DMA channels transfer complete.
The "request line number" triggering STM32 MDMA is the STM32 DMAMUX channel
id set by stm32-dmamux driver in dma_spec->args[3].
stm32-dma driver fills the struct stm32_dma_mdma_config used to configure
the MDMA with struct dma_slave_config .peripheral_config/.peripheral_size.
