The SNDRV_PCM_INFO_BATCH will be added back based on the dmaengine driver's capabilities. Patches for edma dmaengine driver has been prepared to suppress the interrupts. We can add this flag right away and have the benefit of not having interrupts during audio activity when the edma and ASoC patches are in the same tree.

Use the edma-pcm with AM335x and AM437x SoCs. Keep using the davinci-pcm for daVinci devices, they can be switched to use the dmaengine based driver later when they are verified to work correctly.
