Ulf Hansson b9795a3e4e PM: domains: Enable dev_pm_genpd_suspend|resume() for suspend-to-idle
The dev_pm_genpd_suspend|resume() have so far only been used during the
syscore suspend/resume phases. However, during suspend-to-idle, where the
syscore phases doesn't exist, similar operations are sometimes needed.

An existing example are the timekeeping_suspend|resume() functions, which
are being called both through a registered syscore ops during the syscore
phases, but also as regular functions calls from cpuidle (via
tick_freeze()) during suspend-to-idle.

For similar reasons, let's enable the dev_pm_genpd_suspend|resume() APIs to
be re-used for corresponding CPU devices that are attached to a genpd,
during suspend-to-idle.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
