Enable config for dmaengine based Tegra APB DMA driver and disable the legacy APB DMA driver (SYSTEM_DMA).

Laxman, if I apply this series to next-20120816 (plus a few patches in my local work branch plus the CPU hotplug patches from Joseph, although I suspect none of that matters), then audio playback on Tegra20 is broken; the pitch is far too high. Audio playback on Tegra30 works as expected.
