This patch adds ALSA support for the Audio Bistream DAC found on Atmel AVR32 devices. The ABDAC is an Atmel IP which might show up on AT91 devices in the future, hence making a generic driver which can be utilized by AT91 arch if needed. Datasheet describing the ABDAC peripheral is available in the AT32AP7000 datasheet, http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Tested on ATSTK1006 + ATSTK1000 with a class D amplifier stage.
