Use the dmaengine based Tegra APB DMA driver for

Because generic soc-dmaengine-pcm uses the DMAs API
based on dmaengine, using the exported APIs provided
by this generic driver.
The new driver is selected if legacy driver is not
selected and new dma driver is enabled through config
file.

(Tested on Cardhu/Tegra30. It fails on Whistler/Tegra20, but I assume
that's due to a bug in the dmaengine driver not this patch. There won't
be a regression when applying this patch since we haven't switched to
dmaengine as the default yet).
Are you taking this patch?
I have other independent patch for the writecombine dma support in pcm
memory library and wanted to avoid any merge conflicts.
So if it goes in your tree then the other patch also need to go in your
tree.
