[RESEND PATCH v4] Sound: PXA: Fix settings of PXAxxx DMA

[petr.cvek@tul.cz (Petr Cvek)]

Fix PXA DMA autoincrementation, so capture will not use playback settings
(incrementation in register space instead in target buffer).

Regression from:
  'commit d65a14587a9be853a887a1407db133df1fb68e29 ("ASoC: pxa: use snd_dmaengine_dai_dma_data")'
