[PATCH] staging: sm750: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

Convert the deprecated SIMPLE_DEV_PM_OPS to DEFINE_SIMPLE_DEV_PM_OPS
and pm_sleep_ptr().

This lets us drop the __maybe_unused annotations from the suspend
and resume callbacks, also reduces kernel size in case CONFIG_PM
or CONFIG_PM_SLEEP is disabled.
