61fa627f74 doc: Terminology change - signalling -> synchronization
The kernel's services previously referred to as "signalling services",
which include object types such as semaphores, events, and mutexes,
are now referred to as "synchronization services". This term more
clearly conveys their use as a means to synchronize the operation
of two or more entities within the kernel.

93b0ced44b Order hardware and device initialization
The initialization procedures need to be called in the
following order:
- basic hardware initialization;
- devices initialization;
- hardware clock initialization, that the kernel needs to
  run the kernel server.
This way, the board initialization routines is placed
to the pure_early_init level to make sure it runs first,
all device initialization procedures run at pure_init level,
so they are initialized early enough to be used for debugging
if needed. Hardware clock initialization is placed on
nano_early_init level to make sure hardware clock is initialized
just before the kernel server starts.

f06cae3775 samples/benchmark/footprint-min: disable UART console and serial
Previously, CONFIG_PRINTK being false means none of functions related to
the UART console and serial are compiled into the binary. This
effectively means UART console and serial drivers are disabled.
By decoupling serial drivers from console related configs, additional
options are needed to disable serial drivers and UART console driver
itself. So add those options here to disable UART console and serial,
or else the resulting binaries will be too bloated.

ad2d29689e console: uart_console: decouple uart console init from UART init
With this, the UART console has its own initialization which is not
dependent on UART init routines.

This will allow the app to utilize all UARTs for other purposes,
instead of always reserving one for console. Future patch
will enable this choice.

Note that the console init is effectively demoted to pure_init
from pure_early_init. The UART console depends on UART being
initialized, but there is no deferred init at this point.
So this initializes the console a bit later than UARTs,
simply to make sure the UART is initialized before using it.
Once there is a mechanism for some type of deferred initialization,
the UART console init can be promoted back to pure_early.

2fd29e2667 serial: converting to new driver initialization model
This restructures the device structs and now utilizes the new
driver initialization model. This is another step towards
converting the serial driver to the new driver model.

Note that the serial driver does not initialize the hardware
unless it is being used by another driver. The configuration
of the serial port needs to be done by the driver utilizing
the port (e.g. baud rate, interrupt priority, etc.).
Therefore, some serial ports are declared but not exactly
configured.

Also note that the UART console is being initialized at
the same time as the serial port. This will be removed
in future patch, so the UART console driver will do
its own initialization.

d3084b41e6 test_task: improve task_sleep test reliability on QEMU
The test was doing some weird dance for computing the time the main task
had slept, context switching between the main task and a helper task.
The tick timestamp that marks the start of the sleep duration, which
should be taken before the main task goes to sleep actually was taken
after it went to sleep, by the helper task. This lead to weird results
sometimes on QEMU, where the main task would report that it had slept
for less time than requested.

Now instead, the main task takes its own tick timestamps, just before it
goes to sleep and right when it awakens.

The helper task takes a timestamp as well, to verify that it did do busy
work while the main task was sleeping. However, some error is allowed
there to compensate for some QEMU weirdness.
