dmaengine: hisilicon: Add Kunpeng DMA engine support
This patch adds a driver for HiSilicon Kunpeng DMA engine. This DMA engine
which is an PCIe iEP offers 30 channels, each channel has a send queue, a
complete queue and an interrupt to help to do tasks. This DMA engine can do
memory copy between memory blocks or between memory and device buffer.
