As RTT is used by more subsystem in Zephyr, initialization is moved
from RTT console and RTT logger backend to common kernel init phase.

In an effort to reduce the number of CONFIG_ defines in dts files, we
can remove CONFIG_MCUMGR_SMP_UART and just always set
'zephyr,uart-mcumgr' as there is no harm to always having this set for
those board dts files that define the property.

This commit introduces k_sleep() return value, which provides

not-zero, the thread slept shorter than requested, which is

This commit fixes the issue with non-default max packet size (<64).
The max packet size value was not passed to low-level driver
in norfic hal (nrfx_usbd) causing 64-byte being send regardless of
configured endpoint size. Size mismatch results in communication
error on Linux hosts.

__cxxabiv1 is an internal namespace used by GNU's libstdc++.
When linking with C++ standard library (libstdc++),
__cxxabiv1::__class_type_info is already defined inside.
If user code contains virtual classes,
__cxxabiv1::__class_type_info is defined twice.

The entropy_nrf_get_entropy_isr(), which is specific to this driver,
is in fact equivalent of generic entropy_get_entropy_isr(..., 0).
This commit removes the entropy_nrf_get_entropy_isr() function
and replaces its usage by call to generic entropy API.

The old algorithm managing random number pools was inefficient and
prone to race conditions. Moreover, its behaviour was not compatible
with the API (provided buffers were filled from the end, leaving
beggining of the buffer untouched if there was not enough random data).
The new implementation is a bit faster and it is race-free as long as
all callers of the entropy_get_entropy_isr() are executed in
"run-to-completion" mode.

The entropy_nrf5_get_entropy_isr(..., ENTROPY_BUSYWAIT)
unconditionally started and stopped hardware random number generator
disrupting management of random data pools implemented by the driver.
Moreover, simultaneous call to mentioned function from different
priorities led to hangup of lower priority call as hardware was
stopped by higher priority call while the other one waited for data.
This commit solves mentioned problems by moving the responsibility
for stopping hardware to the interrupt handler. As result hardware
is stopped only when there is no blocking calls to the
entropy_nrf5_get_entropy_isr() as well as all random data pools
are full.
This commit also fixes interrupt management in the mentioned
function, as previous implementation unconditionally enabled
interrupt causing problems similar to the described above.

Neither entropy_nrf5_get_entropy_isr() nor isr() protected
access to hardware. As result in some situations a random value
could be "stolen" by a higher priority call interrupting one
of the mentioned functions.
This commit solves this problem by introducing random_byte_get()
which accesses hardware atomically.
