Peter Ujfalusi 7b73a9c8e2 slimbus: qcom-ngd-ctrl: Use dma_request_chan() instead dma_request_slave_channel() ...

dma_request_slave_channel() is a wrapper on top of dma_request_chan()
eating up the error code.

By using dma_request_chan() directly the driver can support deferred
probing against DMA.
