The 'zephyr,memory-region-mpu' property was addede gqas a
convenient way to create and configure MPU regions using information
coming from DT. It has been used a lot since it was introduced so I
guess we can consider it a Zephyr success story ™ .
Unfortunately it has been proved to be a bit limited and with some
important limitations:
1. It was introduced as a property of the compatible
zephyr,memory-region that is used to create linker regions and
sections from DT data. This means that we can actually create MPU
regions only for DT-defined regions and sections.
2. The naming is unfortunate because it is implying that it is used only
for MPU.
3. It is misplaced being in include/zephyr/linker/devicetree_regions.h
and still it has nothing to do with the linker at all.
4. It is exporting a function called LINKER_DT_REGION_MPU that again has
nothing to do with the linker.
Point (1) is also particularly limiting because it is preventing us to
characterize memory regions that are not generated using the
'zephyr,memory-region' compatible, like generic mmio-sram regions.
While we fix all the issues, we also want to extend a bit the range of
usefulness of this property. We are renaming it 'zephyr,memory-attr' and
it is now carrying information about the type of memory the property is
attached to (cacheable, non-cacheable, IO, eXecutable, etc...). The user
can use this property and the DT API coming with it to act on the memory
node it is accompanied by.
We are still providing the DT_MEMORY_ATTR_APPLY() macro that can be used
to create the MPU regions as before, but we are adding also a
DT_MEMORY_ATTR_FOREACH_NODE() macro that can be used to cycle through
the memory nodes and act on those.

Changed initial guess from a simple x/3 to dividing the exponent by 2.
This makes large or small numbers like 10e10 and 01e-10 converge in a few
loops.
Added a loop counter to ensure that the algorithm breaks out of the loop in
the case that the algorithm doesn't converge (toggling between two
numbers).
Added test cases for sqrt and sqrtf in libc. Tested with a range of numbers
between 10e10 and 10e-10. Verify good accuracy in test case.

Usage of 64-bit address constants from devicetree without a
UINT64_C wrapping macro results in the following warning and the
cut-off of the address value:
"warning: integer constant is so large that it is unsigned"
This change extends devicetree API adding few wrappers over the
address constant getters which add ULL size suffix to an
address integer literal when the appearance of 64-bit address
values is possible

Device dependencies are not always required, so make them optional via
CONFIG_DEVICE_DEPS. When enabled, the gen_device_deps script will run so
that dependencies are collected and part of the final image. Related
APIs will be also made available. Since device dependencies are used in
just a few places (power domains), disable the feature by default. When
not enabled, a second linking pass will not be required.

There's no reason to limit testing floating point printf to platforms with
an FPU; neither the minimal C library nor picolibc even use floating point
instructions for printf. And even if they did, the toolchain should have
soft float support.
However, we do need to restrict picolibc testing to configurations with
floating point printf enabled.

Analog to json_obj_encode vs. json_calc_encoded_len which
calculates the object len using json_obj_encode, introduce
json_calc_encoded_arr_len which calculates the length using
json_arr_encode. That is needed when the object to be encoded
is array on the root level.

Rather than the rings, which weren't shared between userspace and kernel
space in Zephyr like they are in Linux with io_uring, use atomic mpsc
queues for submission and completion queues.
Most importantly this removes a potential head of line blocker in the
submission queue as the sqe would be held until a task is completed.
As additional bonuses this avoids some additional locks and restrictions
about what can be submitted and where. It also removes the need for
two executors as all chains/transactions are done concurrently.
Lastly this opens up the possibility for a common pool of sqe's to
allocate from potentially saving lots of memory.
