[PATCH v1] ASoC: core: Replace dma_request_slave_channel() with dma_request_chan()

Drivers should use dma_request_chan() instead of dma_request_slave_channel().

dma_request_slave_channel() is a simple wrapper for dma_request_chan() eating
up the error code for channel request failure and makes deferred probing
impossible.
