ALSA: ASoC: fix SNDCTL_DSP_SYNC support in Freescale 8610 sound drivers
Upstream-commit-id: bf9c8c9ddef7ef761ae9747349175adad0ef16ce
If an OSS application calls SNDCTL_DSP_SYNC, then ALSA will call the driver's
_hw_params and _prepare functions again. On the Freescale MPC8610 DMA ASoC
driver, this caused the DMA controller to be unneccessarily re-programmed, and
apparently it doesn't like that. The DMA will then not operate when
instructed. This patch relocates much of the DMA programming to
fsl_dma_open(), which is called only once.
