Use the dmaengine based Tegra APB DMA driver for data transfer between SPI fifo and memory in place of legacy Tegra APB DMA.

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).
