avr32: at32ap700x: setup DMA for ABDAC in the machine code
This patch will adjust the setup the DMA controller for the Audio Bistream DAC in the at32ap700x machine code. This setup matches the new ALSA driver for the ABDAC. Tested on ATSTK1006 + ATSTK1000. This patch will setup the needed platform data for the Audio Bistream DAC used by the Favr-32 board.
