Subject: [PATCH v1 1/1] dmaengine: idma64: switch to DEFINE_SIMPLE_DEV_PM_OPS()

SET_*_PM_OPS() are deprecated, replace it with DEFINE_SIMPLE_DEV_PM_OPS()
and use pm_sleep_ptr() for setting the driver's PM routines. We can now
remove the __maybe_unused qualifier in the suspend and resume functions.
