dmaengine: sh: rz-dmac: Refactor pause/resume code
Subsequent patches will add suspend/resume and cyclic DMA support to the
rz-dmac driver. This support needs to work on SoCs where power to most
components (including DMA) is turned off during system suspend. For this,
some channels (for example cyclic ones) may need to be paused and resumed
manually by the DMA driver during system suspend/resume.
Refactor the pause/resume support so the same code can be reused in the
system suspend/resume path.
