From: Grygorii Strashko <grygorii.strashko@xxxxxxxxxx>
Setting a dev_pm_ops resume callback but not a set of
hibernation handler means that pm function will not be
called upon hibernation.
Fix this by using SIMPLE_DEV_PM_OPS, which appropriately
assigns the suspend and hibernation handlers and move
omap_dmm_resume under CONFIG_PM_SLEEP to avoid build warnings.
