There are few existing user drivers of dw_dmac. They will break as soon as we
remove unused fields from struct dw_dma_slave. This patch focuses to fix these
user drivers to use dma_slave_config() routine.

Several fixes as well where the +1 was missing.

Done via coccinelle scripts like:

@@
struct resource *ptr;
@@

- ptr->end - ptr->start + 1
+ resource_size(ptr)

and some grep and typing.

Mostly uncompiled, no cross-compilers.

This patch increases periods_min to 6 from 4, this will remove any
hickups where the buffer is not filled fast enough from user space.

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.
