[PATCH 14/15] ARM: pxa: change SSP devices allocation

In order to prepare for the dma_slave_map change for SSP DMA channels allocation, the SSP platform devices will now include a platform data structure which in turn selects which dma channel has to be used for data transfers, especially the PCM ones. Signed-off-by: Robert Jarzmik
