dmaengine: dw: fix cyclic transfer setup
Commit 61e183f8 ("dmaengine/dw_dmac: Reconfigure interrupt and chan_cfg register on resume") moved some channel initialisation to a new function which must be called before starting a transfer. This updates dw_dma_cyclic_start() to use dwc_dostart() like the other modes, thus ensuring dwc_initialize() gets called and removing some code duplication.
