From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
If CONFIG_PM is not set, the pm_ptr() will ensure that the struct
dev_pm_ops and callbacks are removed without the need for __maybe_unused
markings.
In this case we can't simply use DEFINE_RUNTIME_DEV_PM_OPS() because
that would provide suspend and resume functions without the
checks the driver is doing before calling runtime_pm functions
(whether the necessary GPIO is provided). It may be possible to
clean that up in future by moving the checks into the callbacks.
