dmaengine: ti: k3-udma: annotate pm function with __maybe_unused
We get a warning when PM is not set:
../drivers/dma/ti/k3-udma.c:5552:12: warning: 'udma_pm_resume' defined but not used [-Wunused-function]
5552 | static int udma_pm_resume(struct device *dev)
| ^~~~~~~~~~~~~~
../drivers/dma/ti/k3-udma.c:5530:12: warning: 'udma_pm_suspend' defined but not used [-Wunused-function]
5530 | static int udma_pm_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~
Fix this by annotating pm function with __maybe_unused
Fixes: fbe05149e40b ("dmaengine: ti: k3-udma: Add system suspend/resume support")
