[PATCH v2 0/5] dma: don't set chancnt

I'm patching dw-axi-dmac to add more features, but I found a small
clean up point and some drivers in drivers/dma/ have the same issue,
so this series comes.

The dma framework will calculate the dma channels chancnt, setting it
is wrong.

NOTE: I leave drivers/dma/ioat/ as is, because its logic have a
heavy dependency on chancnt usage, however it's still doable.

Since v1:
  - collet Acked-by tag
  - fix typo
