ARM: pxa: change SSP DMA channels allocation
Now the dma_slave_map is available for PXA architecture, switch the SSP
device to it.
This specifically means that :
- for platform data based machines, the DMA requestor channels are
extracted from the slave map, where pxa-ssp-dai.<N> is a 1-1 match to
ssp.<N>, and the channels are either "rx" or "tx".
- for device tree platforms, the dma node should be hooked into the
pxa2xx-ac97 or pxa-ssp-dai node.
