spi: davinci: Use dma_request_chan() for requesting DMA channel
With the new dma_request_chan() the client driver does not need to look for the DMA resource and it does not need to pass filter_fn anymore. By switching to the new API the driver can now support deferred probing against DMA. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
