- Remove SYS_ prefix
- shorten POWER_MANAGEMENT to just PM
- DEVICE_POWER_MANAGEMENT -> PM_DEVICE
and use PM_ as the prefix for all PM related Kconfigs

To make it runnable in the sanitycheck necessary to add
capture output, because that sample runs infinite period of time
and can not finished by itself. To avoid timeout error
in the sanitycheck I added capture output for a several times.
Also added one more tag to describe that it is a power
management sample.

Power management sample for that board has very
confusing name that should be changed to something
more understandable.
Current name sample.board.sample.board.mec15xxevb_assy6853
I suggest to have new name
sample.board.power_management.mec15xxevb_assy6853

This provides a better error message when building with CMake and
forgetting ZEPHYR_BASE or not registering Zephyr in the CMake package
registry. See parent commit for more details (split from parent for
better readability).

Add indication when sleep entry/exit counter do not match the test
expectations.
Measure deep sleep entry latency.
Add sleep entry/exit indication via gpios to debug.
Remove unnecessary trailing \n when using logging.

The origin for sleeping for 3ms after coming out of deep sleep
was to wait for PLL to lock so that UART would not send
garbage characters due to incorrect clock. In the deep sleep
code, it spins to wait for the PLL to lock so there is no need
to wait for 3ms in the app. So shorten it like other busy wait.

Threads are being re-used for multiple runs, so it is better to
stop the threads before reusing the variables for new threads.

Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.
