atmel-pcm-dma is not limited to a buffer size of 64kB like atmel-pcm-pdc. Increase buffer_bytes_max to 512kB to allow for higher bit rates (i.e. 32bps at 192kHz) to work correctly. By default, keep the prealloc at 64kB.

Applied, but please look into Lars' suggestion - we should be able to just figure everything out from the DMA controller.

This is definitively on the TODO list.
