From: Fabio Estevam <festevam@denx.de>

The combined usage of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS()
allows the compiler to evaluate if the suspend/resume() functions
are used at build time or are simply dead code.

This allows removing __maybe_unused notations from the suspend/resume()
functions.

Changes since v1:
- Use DEFINE_SIMPLE_DEV_PM_OPS() to fix build warnings.
