SYS_DLIST_FOR_EACH_NODE() is marked as non-safe when an item is removed
from the list while looping over it. This is not true per-se, since the
item, when removed, keeps its next and prev pointers intact; however, it
is true if the item is then put into a list, be it a different one or
the same one. To prevent this, SYS_DLIST_FOR_EACH_NODE_SAFE() must be
used.
_mbox_message_put() can remove items from the rx queue and then put them
in the ready queue: this would cause the loop to start processing other
ready threads as item in the rx queue.
k_mbox_get() also removes items, from the tx queue, but does not seem to
add them to another list; however, it now uses the safe version as well,
since that is the proper usage.

There was a lot of duplication between architectures for the definition
of threads and the "nanokernel" guts. These have been consolidated.
Now, a common file kernel/unified/include/kernel_structs.h holds the
common definitions. Architectures provide two files to complement it:
kernel_arch_data.h and kernel_arch_func.h. The first one contains at
least the struct _thread_arch and struct _kernel_arch data structures,
as well as the struct _callee_saved and struct _caller_saved register
layouts. The second file contains anything that needs what is provided
by the common stuff in kernel_structs.h. Those two files are only meant
to be included in kernel_structs.h in very specific locations.
The thread data structure has been separated into three major parts:
common struct _thread_base and struct k_thread, and arch-specific struct
_thread_arch. The first and third ones are included in the second.
The struct s_NANO data structure has been split into two: common struct
_kernel and arch-specific struct _kernel_arch. The latter is included in
the former.
Offsets files have also changed: nano_offsets.h has been renamed
kernel_offsets.h and is still included by the arch-specific offsets.c.
Also, since the thread and kernel data structures are now made of
sub-structures, offsets have to be added to make up the full offset.
Some of these additions have been consolidated in shorter symbols,
available from kernel/unified/include/offsets_short.h, which includes an
arch-specific offsets_arch_short.h. Most of the code include
offsets_short.h now instead of offsets.h.

Add spi flash erase boundary check. The erase boundary must be
4K-aligned. So, the flash chip will round down an non-4K aligned
address to the nearest 4K boundary automatically. As a result of
this, the erase area will start from a different address (if the
API caller specifies an non-4K alighed address), even though the
size of the erased area is the same as what is specified by the
API caller. Let's add a boundary check to make sure the starting
address (from the API caller) is 4K aligned.
Correct an error in the highest address check. Because of the
error, the erase api call will fail if the flash's highest
address byte is involved.

The API to disable _sys_soc_resume notification is currently
called _sys_soc_disable_wake_event_notification. This is
misleading because it is possible that the ISR from which
_sys_soc_resume is called could be from a different interrupt
with higher priority that happened before interrupts were
enabled. More accurately, it is a notification of exit from
kernel idling after pm operations.

_sys_soc_resume hook is over loaded to handle to different
scenarios. It is primarily called to notify exit of kernel idling
after PM operations. It is also used to notify exit from deep sleep.
This is very confusing and also makes the implementation of the
hook function very difficult because of very different conditions
involved in the 2 different use cases. Further, users may not require
either or both use cases depending of their custom boot flow and
power state handling. To simplify, create a separate hook for the
purpose of deep sleep exit notification. Use the existing one to
only notify kernel idling exit after PM operations.

The driver exposes a public uart driver API and allows to register up
to five UART devices: from 'UART_0' to 'UART_4'. The driver performs
the required pinmux, the clock control configuration is left to the
platform.
The driver has been verified to work with the Hello World sample
