1976f33e87 drivers: mbox: Introduce MBOX driver class
One limitation of the current IPM API is that it is assuming that the
hardware is only exporting one single channel through which the data can
be sent or signalling can happen.

If the hardware supports multiple channels, the IPM device must be
instantiated (possibly in the DT) several times, one for each channel to
be able to send data through multiple channels using the same hw
peripheral. Also in the current IPM API only one callback can be
registered, that means that only one driver is controlling all the
signalling happening on all the channels.

This patch is introducing a new MBOX API that is supporting
multi-channel signalling and data exachange leveraging and extending the
previous (and outdated) IPM API.

9239fd4a90 pm: device: Simplify device pm states
As discussed in issues/38619, this commit aims to simplify device
power management. It was removed PM_DEVICE_SATE_LOW_POWER.
The power subsystem now doesn't need to figure out which device state to
use of a given system power state. It just suspend and resume devices.

Devices now just need to respond to ACTIVE and SUSPEND and OFF actions
and they are free to use any particular substate they have when the
subsystem asks to suspend. They also don't need to worry about states
transitions (unless they have multiple substates) because the system
will just request them to suspend if they are active and vice-versa.

43cb00df08 multi_heap: Introduce shared multi-heap memory pool manager
The shared multi-heap memory pool manager uses the multi-heap allocator
to manage a set of reserved memory regions with different capabilities /
attributes (cacheable, non-cacheable, etc...) defined in the DT.

The user can request allocation from the shared pool specifying the
capability / attribute of interest for the memory (cacheable /
non-cacheable memory, etc...)

fdeaa9103e random: deprecate XOROSHIRO_RANDOM_GENERATOR
Deprecate the xoroshiro128+ PRNG algorithm in favour of xoshiro128++.
xoshiro128++ is a drop-in replacement which is invisible from the user
perspective.

xoroshiro128+ is unsuitable because it is explicitly a floating-point
PRNG, not a general-purpose PRNG. This means that the lower 4 bits of
the output are actually linear, not random (from the designers,
https://prng.di.unimi.it/). This means 1/8th of the generated data is
not random.

Additionally, xoroshiro128+ is not a 32bit algorithm, it operates on
64bit numbers. For the vast majority of Zephyr devices, this makes the
PRNG slower than it needs to be. The replacement (xoshiro128++) is
32bit, with no loss in state space (still 128 bit).

2b2f2c94a7 api: devicetree.h is stable
This API meets the requirements for marking an API stable:

- Test cases for the new API with 100% coverage: yes;
  we have had coverage for every API macro since the beginning.

- Complete documentation in code. All public interfaces shall be
  documented and available in online documentation.: yes, in the
  reference documentation:
  https://docs.zephyrproject.org/latest/reference/devicetree/api.html

- The API has been in-use and was available in at least 2 development
  releases: yes; this API ws introduced in v2.3.

The basic design involving node identifiers and the macros that create
and operate on them has not changed since the API was introduced, and
it is in widespread use throughout the tree. As we head into a new
LTS, it's time to mark it stable.

This is more of an acknowledgement of reality than a big change, as I
don't see any backwards incompatible changes since the API was first
introduced in v2.3. (We have deprecated a lot of label related macros
that are no longer required now that we have DEVICE_DT_GET and
friends, but they're still there, and we're still testing them, just
as if this were a stable API.)
