dmaengine: k3dma: Add CONFIG_PM_SLEEP to suspend/resume functions 

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.

drivers/dma/k3dma.c:790:12: warning: 'k3_dma_suspend' defined but not used [-Wunused-function]
drivers/dma/k3dma.c:806:12: warning: 'k3_dma_resume' defined but not used [-Wunused-function]
