drivers, pch_dma: Fix warning when CONFIG_PM=n.
When CONFIG_PM=n, we get the following warning: drivers/dma/pch_dma.c:741: warning: ‘pch_dma_suspend’ defined but not used drivers/dma/pch_dma.c:755: warning: ‘pch_dma_resume’ defined but not used To fix it, wrap pch_dma_{suspend,resume} and pch_dma_{save,restore}_regs functions with CONFIG_PM.
