This series add NVIDIA Tegra's APB dma controller driver based on dmaengine.
There is already old driver in mach-tegra/dma.c and we want to get rid
of this old style driver which exposes private apis.
Once this driver get through, there will be series of patches to move all
existing driver to use the dmaengine based driver and old mach-tegra/dma.c
will get deleted. This driver has following feature than old one:
- better queue managment.
- Cyclic transfer supports.
- Platform driver.
- Full support for device tree.
- Multiple bug fixes over old driver.

Changes from V1:
- Incorportaed review comments from Vinod.
- get rid of the tegra_dma header.
- Having clock control through runtime pm.
- Remove regmap support.
