dts: bindings: dma controller supports mem2mem transfer This checks if the DMA controller supports or not the memory-to-memory transfers. For DMA Version1, in the stm32f2xx, stm32f4xx, stm32f7xx series, only DMA instance 2 is able to transfer mem-to-mem. For other series, with DMA Version2, there is no such a limitation.
