Replace the deprecated SIMPLE_DEV_PM_OPS with DEFINE_SIMPLE_DEV_PM_OPS. This also drops the __maybe_unused annotations on the suspend/resume callbacks, since pm_sleep_ptr() inside the new macro already handles the case where CONFIG_PM_SLEEP is disabled. When CONFIG_PM=y but CONFIG_PM_SLEEP=n (a valid configuration that enables runtime PM but disables system suspend/hibernation), this keeps a completely empty dev_pm_ops structure -- all callbacks are NULL -- as dead code in the object file.Modify pm_ptr to pm_sleep_ptr.
