Marek Szyprowski ba3d6f8f10 serial: samsung: Simplify DMA engine initialization code ...

dma_request_slave_channel_compat() requires filter function and mask, which
are not needed on device tree based platforms, so simplify the code by
calling the more appropriate dma_request_chan() function. This additionally
gives us proper error handling, because the new function returns error
codes instead of NULL on failure.
