dmaengine: sa11x0: Mark PM functions as __maybe_unused
Without CONFIG_PM_SLEEP, the runtime suspend/resume functions
are unused, producing a warning:
../drivers/dma/sa11x0-dma.c:1042:12: error: 'sa11x0_dma_resume' defined but not used
../drivers/dma/sa11x0-dma.c:1004:12: error: 'sa11x0_dma_suspend' defined but not used
