[PATCH v2 2/7] ASoC: sprd: Replace dma_request_slave_channel() by dma_request_chan()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

Replace dma_request_slave_channel() by dma_request_chan() as suggested
since the former is deprecated. With this, propagate all possible errors
to the caller.
