Created unified kernel build setup for the power_mgr sample
app. Currently it shares the same source file between
micro and unified kernels. This is to help test and add new
features from unified kernel. In future, separate source will
be created for unified kernel. After transition is completed,
microkernel version will be removed.

Simplified some documentation, removing inconsistencies and making
it easier to understand by separating PM infrastructure areas and
soc specific components that implement the hooks.
Removed the DEVICE_SUSPEND_ONLY policy as it is redundant and
causes high complexity in the flow. It is also not practical
to use it because it was meant to be used without doing CPU or SOC
low power state operations. This means it would do device PM
operations in the ISR of the system timer used by the scheduler.
This can disrupt the scheduler time.
Added a check of a flag around the notification sent from the ISR
of the wake event and created APIs to set/clear it. This will
allow disabling the notification when not needed from
_sys_soc_suspend().

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.

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.
