[PATCH v2] iio: cros_ec: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

Convert 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 resume callbacks,
and reduces kernel size when CONFIG_PM or CONFIG_PM_SLEEP is disabled.

Changes in v2:
- Use EXPORT_GPL_SIMPLE_DEV_PM_OPS for cros_ec_sensors_pm_ops
- Wrap to 75 ish chars for commit messages.
