The Freescale Elo DMA driver binds to all DMA channels in the device

compatible property
for the DMA channels needed by the sound drivers to "fsl,ssi-dma-
channel".
This works because the sound drivers don't actually check the
compatible
property when it grabs DMA channels.
Also update dma.txt and ssi.txt with this information.

Break this into two patches. The second one should just be the .dts
and specifically say "on the MPC8610 HPCD board we use SSI and thus
the dma channel is not available for general purpose use"...
