Manuel Lauss ffc4fdbbe1 ASoC: fix au1x platform
This patch fixes up the au1x audio platform after the multi-component
merge:
- compile fixes and updates to get DB1200 platform audio working again,
- removal of global variables in AC97/I2S/DMA(PCM) modules.

The AC97 part is limited to one instance only for now due to issues
with getting at driver data in the soc_ac97_ops.
