Subject: ASoC: pxa: pxa2xx-ac97: fix dma requestor lines

commit 8811191fdf7ed02ee07cb8469428158572d355a2 upstream.

PCM receive and transmit DMA requestor lines were reverted, breaking the
PCM playback interface for PXA platforms using the sound/soc/ variant
instead of the sound/arm variant.

The commit below shows the inversion in the requestor lines.
