powerpc/85xx: fix compatible properties of the P1022DS DMA nodes used for audio

powerpc/85xx: fix compatible properties of the P1022DS DMA nodes used for audio

commit b2e0861e51f2961954330dcafe6d148ee3ab5cff upstream.

In order to prevent the fsl_dma driver from claiming the DMA channels that the
P1022DS audio driver needs, the compatible properties for those nodes must say
"fsl,ssi-dma-channel" instead of "fsl,eloplus-dma-channel".
