dmaengine: hisilicon: Adapt DMA driver to HiSilicon IP09
The HiSilicon IP08 and HiSilicon IP09 are DMA iEPs, they
have the same pci device id but different pci revision.
Unfortunately, they have different register layouts, so
the origin driver cannot run on HiSilicon IP09 correctly.
This patch enables the driver to adapt to HiSilicon IP09.
HiSilicon IP09 offers 4 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.
