A race condition was identified during the initialization of the
driver when the trigger function is enabled. This exposed two issues:
1 - The fxas21002_handle_int is trying to acquire the semaphore before
it gets initialized. To solve this we need to initialize the
semaphore before calling the fxas21002_trigger_init function.
2 - During the fxas21002_trigger initialization the i2c bus is used
(from fxas21002_handle_int function) at the same time as the
fxas21002_set_power is being called. To fix this we need to
initialize the semaphore with 0 and just release it after calling
the fxas21002_set_power function in the fxas21002_int

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.
In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.

Adds dts bindings for the fxas21002 interrupt pins to all boards that
have this sensor.
The fxas21002 driver is currently only aware of one sensor interrupt
pin, therefore the routing of INT1 or INT2 to the driver is handled in
each board's dts.fixup.
The fxas21002 sample application has been broken since the refactoring
of the mcux gpio driver to dts in commit
4e8f29f319. The sample is now fixed.

Adds dts yaml bindings for the fxas21002 sensor to allow the sensor
driver name, i2c driver name, and i2c address to be extracted from dts
instead of kconfig.

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

Change the common "init with 0" + "give" idiom to "init with 1". This
won't change the behavior or performance, but should decrease the size
ever so slightly.
This change has been performed mechanically with the following
Coccinelle script:
@@
expression SEM;
expression LIMIT;
expression TIMEOUT;
@@
- k_sem_init(SEM, 0, LIMIT);
- k_sem_give(SEM);
+ k_sem_init(SEM, 1, LIMIT);

Update the MCUX I2C driver and related platforms to get their I2C
information from the device tree. We also updated a few of the sensor
drivers found on the FRDM & Hexiwear boards to get their I2C bus name
from the device tree instead of directly from Kconfig.

This reverts commit e60af3be66.
We revert this as we intent to move away from {u}int{8,16,32,64}_t types
to our own internal types for sized variables so we shouldn't need the
PRI macros anymore.

To allow for various libc implementations (like newlib) in which the way
various {u}int{8,16,32}_t types are defined vary between both libc
implementations and across architectures we need to utilize the PRI
defines.
