Added changes to enhance device suspend/resume involving
core devices used by OS and app. Updated with Deep Sleep
power policy usage example. Moved the arch/soc dependent
code to soc/arch dependent areas in Zephyr in a separate
patch. This app now uses api that abstracts the soc/arch
details in handling power states.

This patch adds a reference Power Management Application (PMA) for
Quark SE based platforms.
This application demostrates how to interact with the PM subsystem
and how to put the SoC in different power states. The application
"modus operandi" is very simple. The application keeps transiting
between all power states supported by Quark SE SoC. For now, C1,
C2 and C2LP CPU states are implemented. Upcoming patches will
add support for the remaining states (LPS and Sleep states).

To show possible usage of the device_busy_xxx() APIs.
Meant to show how drivers and power policy manager can use them.

Added device power management hook infrastructure. Added
DEVICE_INIT_PM and SYS_INIT_PM macros that creates device
structures with the supplied device_ops structure containing
the hooks.
Added example support in gpio_dw driver. Updated the sample
app and tested using LPS and Device Suspend Only policies.

Sample implementation of a power manager app that uses the zephyr
power management infrastructure. This app demonstrates use of the
hooks to implement Low Power State and Tickless idle power saving
policies.
Tested on quark_se.

A template app that defines the power management hooks and
enables the power management related CONFIG flags. This
app will enable build testing of power management code inside
the CONFIG flags.
