Commit Message

  Since Baytrail pinctrl device is not attached to acpi_lpss_pm_domain,
runtime PM serves no purpose here. Drop it and switch to pm_sleep_ptr()
as now we only have suspend and resume handles in place.

No functional impact.

TODO:
Consider moving to DEFINE_LATE_DEV_PM_OPS() in the future once we have
enough users to account for its introduction.

This is not related to the commit message.
I'll drop it.

Ah, and next time, please do a cover letter for the series, it can be
better managed from maintainer perspective.

I just realized I forgot to add pm.h here.
I'll send out a v2.
