dmaengine: st_fdma: Add STMicroelectronics FDMA engine driver support
This patch adds support for the Flexible Direct Memory Access (FDMA) core driver. The FDMA is a slim core CPU with a dedicated firmware. It is a general purpose DMA controller capable of supporting 16 independent DMA channels. Data moves maybe from memory to memory or between memory and paced latency critical real time targets and it is found on al STi based chipsets.
