This series first fix a bug related with runtime pm. Then do three clean
up. After that, we add three new features: per channel irq support,
dma-channel-mask support and polled mode support.

Since v3:
  - rebase on the latest rc1

Since v2
  - fix typo
  - add reason why we need to runtime resume before reading reg in
    commit msg

Hi Vinod,

I still kept patch2 in v2, because I think the irq has been disabled
from the dw-axi-dma side, so the irq won't be fired any more. If you
prefer to keep the devm_free_irq() just ignore patch2.

Thanks a lot.
