ASoC: tegra: use dmaengine based dma driver
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.
