Replace the deprecated SIMPLE_DEV_PM_OPS with DEFINE_SIMPLE_DEV_PM_OPS
and wrap the struct assignment with pm_sleep_ptr(). The old code keeps
a completely empty dev_pm_ops structure -- all callbacks are NULL --
as dead code in the object file when CONFIG_PM_SLEEP=n, because
SET_SYSTEM_SLEEP_PM_OPS() expands to nothing while __maybe_unused on
the struct only silences the warning without removing the struct.
Switching to DEFINE_SIMPLE_DEV_PM_OPS() lets pm_sleep_ptr() eliminate
the callback references at compile time, and wrapping the struct
assignment with pm_sleep_ptr() drops the entire structure when
CONFIG_PM_SLEEP is disabled, instead of retaining an empty one.
