Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

nrf SOCs use external timer for measuring benchmarking stats.
Earlier this timer is programmed in 24 bit mode, due to which
is is getting expired in some of benchmark stats like mutex
lock/unlock. So configuring to 32 bit mode to avoid overflow.

Some of benchmark stats were not reported for nrf52/52 based SOCs.
This was because nrf based SOCs use external timer.
In timing info some of benchmark stats still use systick based APIs.
Due to which benchmarking number was not getting reported. So change
it to timer based for nrf.

nrf SOC uses nrf rtc timer (not sys tick), which is 32kHz,
whereas CPU runs at higher speed (nrf52 runs at 64MHz).
So 32Khz is too slow to measure critical kernel parameters.
This patch does :-
1. Add support for nrf SOC for timing_info benchmarking.
2. Uses SOC timer to measure kernel parameters.

The API/Variable names in timing_info looks very speicific to
platform (like systick etc), whereas these variabled are used
across platforms (nrf/arm/quark).
So this patch :-
1. changing API/Variable names to generic one.
2. Creating some of Macros whose implimentation is platform
depenent.

This will prepare test cases and samples with metadata and information
that will be consumed by the sanitycheck script which will be changed to
parse YAML files instead of ini.

The error was generated by a piece of code that is
not currently being used. This piece of code was kept to measure
the overhead caused by the benchmarking code on x86.
