The whole "tty" concept is conceived around efficient
interrupt-driven operation. However, it's beneficial to add
non interupt-driven operation under the same API:
1. Wider usecase coverage in general.
2. Allows to use the same familiar API (based on POSIX concepts)
even for UART implementations without interrupt support.
3. Allows to switch operation dynamically based on the needs.
For example, if the system is in degraded mode and interrupt
handling cannot be trusted/disabled, allows to still output
diagnostic information to user. This was the original motivation
to provide such a mode, to support logging subsystem's "panic"
mode.
To implement this feature, tty_set_rx_buf() and tty_set_tx_buf()
functions are provided, allowing to reconfigure buffers used
dynamically. If configured buffer length is 0, the operation
switched to unbuffered.

We only need to add the reg property in flash0 and sram0,
in the different DTS headers for the nRF SOCS. We do not
seem to need to define the nodes again. This commit applies
this simplification for flash and sram sizes definition.

Aid user in understanding what CMake expects of:
* Document and add CMAKE_SYSTEM_VERSION
* Document CMAKE_SYSTEM_NAME
* Document CMAKE_SYSTEM_PROCESSOR
* Document BUILD_SHARED_LIBS
* Document Policies CMP0002, CMP0079
CMAKE_SYSTEM_VERSION is required officially by CMake, but appears
unused -- at least now we are compliant.

Nordic UICR are non-volatile memory registers for
configuring user-specific settings. Basically it is subset of flash
memory available in the SoC.
Add support for operations on NVM which belongs to UICR.
UICR are written or read as ordinary flash memory.
For erasing UICR it is required to call erase with UICR start
address and its size (this is caused by what hardware supported).

nRF 16MHz clock is used by both BLE radio and temperature sensor.
During BLE connection if the temperature sensor is also used then
at some point assert condition is hit in temp_nrf5_sample_fetch().
The error code -EBUSY seen during clock_control_off() is that clock
is no longer needed for the temperature sensor, but it cannot be
just turned off because it is still needed for BLE connection.

ieee802154_nrf5 uses net_analyze_stack function in a loop, which
prints logs at inf level. As net_core's log level is used in
this function which by default is set to inf, it kept spamming stack
usage logs.
Prevent this behavior by adding additional log level check in the driver
itself, so that this log will only be printed if
IEEE802154_DRIVER_LOG_LEVEL is set to debug.

If burst of log messages was passed to the shell log
backend, it was likely that messages were lost because
shell had no means to control arrivals of log messages.
Added log message enqueueing timeout to the shell instance
to allow blocking logger thread if short-term arrival rate
exceeded shell capabilities.
Added kconfig option for setting log message queue size
and timeout in RTT and UART instances. Added section in
shell documentation which explains interaction between
