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.
