+HISILICON Accelerator DMA Driver

How is it different of drivers/dma/hisilicon/ ?

If it is the same hardware (Kunpeng),
I recommend having a single driver, or a single directory.
Also we already have a driver named "acc" in baseband.
they belong to different hardware IP of Kunpeng platform, /dma/hisilicon
is the PCIE subsystem DMA's driver, while this acc is the
Accelerator(ZIP) subsystem DMA's driver. they don't exist in the same
specific Kunpeng Soc.
a single driver will add complex.
as for a single directory, should we do for all vendor? I see there
are dpaa and dpaa2, ioat and idxd both belong to vendor platform.
if there are no rule to have same name with different subsystem driver,
I prefer keep it.
