A GPIO's parallel output bit in the parallel output
registers is read-only until the AOD bit is set to 1
in the pin's control registers. The proper sequence to
preset the state of an output pin is:
Configure pin as input with AOD=1 in the control register
Set pin state in the parallel output register
Set direction to output in the pin's control register.

This commit ensures that roots are being converted to posix paths.
This fixes the issue where windows style path (containing `\`) would
result in DTS dependency file to contain mixed style path separator and
thus causing Ninja to re-invoke CMake in an endless loop.

Users testing beacon capability will likely want to see the beacons in
a sniffer tool. Switch to an advertising mode that uses a persistent
known address, and display that address on the console output.
This also demonstrates techniques to retrieve the advertising address
where one is known.

Document the distinction between the existing non-connectable
advertising configurations, and add one that uses identity which will
be the same for all beacons.

Found out that important requirements are not tested by current
kernel objects tests. Decided to fix that situation
New added tests:
1. test_kobj_assign_perms_on_alloc_obj()
Create kernel object semaphore, dynamically allocate it from the
calling thread's resource pool.
Check that object's address is in bounds of that memory pool.
Then check the requestor thread will implicitly be assigned
permission on the allocated object by using
semaphore API k_sem_init()
2. test_no_ref_dyn_kobj_release_mem()
Dynamically allocated kernel objects whose access is controlled by
the permission system will use object permission as a reference count
If no threads have access to an object, the object's memory released.
3. test_krnl_obj_static_alloc_build_time()
Take addresses of the kernel objects which are statically allocated
during the build time and verify that they are not null.
That kernel objects shouldn't require manual
registration by the end user.
4. Clean-up. Removed unused variable from userspace test.

The IIS2ICLX is a high-accuracy. ultra-low noise, low-power
two-axis linear accelerometer which can be interfaced through
either I2C or SPI bus.
Its high accuracy, stability over temperature and repeatability
make IIS2ICLX particularly suitable for inclination measurement
for industrial applications (inclinometers).

Removed SPI peripheral disabling when switching DMA to another buffer.
When using hardware chip select this would cause to stop driving

when used software CS.

When CONFIG_ARCH_HAS_CUSTOM_BUSY_WAIT is not defined, cycles_to_wait
is calculated using a division operation. This calculation could take a
significant amount of time (a few microseconds on some architectures,
depending on the system clock).
In the special case of zero usec_to_wait, the function should return
immediately rather than spend time on calculations.
For example, in spi driver (spi_context.h, _spi_context_cs_control()),
k_busy_wait() can be called with zero delay. This can increase spi
transaction time significantly.
Another improvement, is moving the start_cycles initialization
before cycles_to_wait calculation, so the time it takes to calculate
cycles_to_wait will be taken into account.

Add the first API functions that directly deal with node dependency
ordinals as determined by edtlib:
- DT_DEP_ORD(node_id): node_id's ordinal
- DT_REQUIRES_DEP_ORDS(node_id): list of dep ordinals for node_id's
direct dependencies
- DT_SUPPORTS_DEP_ORDS(node_id): list of dep ordinals for nodes
depending directly on node_id
- DT_INST_ equivalents
This is not meant to be an exhaustive set of macros related to
dependency ordinals; rather, it's a starting out point meant to enable
initial struct device dependency tracking work. We can add more if
needed.
