The fixed number of 24 RTEs is a legacy thing, and long gone by now.
IOAPICs expose the maximum number of RTEs they have via the version
register, so let's use it.
This avoids to manually tweak a Kconfig option (which is now removed)
and fixes the RTE number for all x86 targets relevantly.

Add a data validation callback to the resource structure, which can be
registered by an application. It allows to verify the data before
actually modifying the resource data.
If the callback is registered for a resource, the data is decoded into a
temporary buffer first, and only copied into the actual resource buffer
if the validation is successfull. If no validation is required (and thus
no callback registered) the resource value is decoded directly into the
resource buffer, as it used to be.

The Xtensa L1 cache layer has straightforward semantics accessible via
single-instructions that operate on cache lines via physical
addresses. These are very amenable to inlining.
Unfortunately the Xtensa HAL layer requires function calls to do this,
leading to significant code waste at the calling site, an extra frame
on the stack and needless runtime instructions for situations where
the call is over a constant region that could elide the loop. This is
made even worse because the HAL library is not built with
-ffunction-sections, so pulling in even one of these tiny cache
functions has the effect of importing a 1500-byte object file into the
link!
Add our own tiny cache layer to include/arch/xtensa/cache.h and use
that instead.

The xtensa atomics layer was written with hand-coded assembly that had
to be called as functions. That's needlessly slow, given that the low
level primitives are a two-instruction sequence. Ideally the compiler
should see this as an inline to permit it to better optimize around
the needed barriers.
There was also a bug with the atomic_cas function, which had a loop
internally instead of returning the old value synchronously on a
failed swap. That's benign right now because our existing spin lock
does nothing but retry it in a tight loop anyway, but it's incorrect
per spec and would have caused a contention hang with more elaborate
algorithms (for example a spinlock with backoff semantics).
Remove the old implementation and replace with a much smaller inline C
one based on just two assembly primitives.
This patch also contains a little bit of refactoring to address the
scheme has been split out into a separate header for each, and the
ATOMIC_OPERATIONS_CUSTOM kconfig has been renamed to
ATOMIC_OPERATIONS_ARCH to better capture what it means.

There was a bunch of dead historical cruft floating around in the
arch/xtensa tree, left over from older code versions. It's time to do
a cleanup pass. This is entirely refactoring and size optimization,
no behavior changes on any in-tree devices should be present.
Among the more notable changes:
+ xtensa_context.h offered an elaborate API to deal with a stack frame
and context layout that we no longer use.
+ xtensa_rtos.h was entirely dead code
+ xtensa_timer.h was a parallel abstraction layer implementing in the
architecture layer what we're already doing in our timer driver.
+ The architecture thread structs (_callee_saved and _thread_arch)
aren't used by current code, and had dead fields that were removed.
Unfortunately for standards compliance and C++ compatibility it's
not possible to leave an empty struct here, so they have a single
byte field.
+ xtensa_api.h was really just some interrupt management inlines used
by irq.h, so fold that code into the outer header.
+ Remove the stale assembly offsets. This architecture doesn't use
that facility.
All told, more than a thousand lines have been removed. Not bad.

pm_power_state_force had two different behavior, if
CONFIG_PM_DIRECT_FORCE_MODE was enabled this function immediately
calls pm_system_suspend() without wait the idle thread. Without this
option enabled, this function will wait for the idle thread run but
will use the given power state instead of asking the policy manager.
The problem in both cases is that the process involves handling
devices and the way that was implemented if at least one device failed
to go to low power or suspended the system power state would not
change / be forced.
This commit simplifies this API removing the conditional behavior
since it is not clear the need for that and effectively, and
immediately, forces the system to go to the given state without
bother with devices.

Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".
Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.
In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.
These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

AArch64 has support for PSCI. This is especially useful for SMP because
PSCI is used to power on the secordary cores.
When the PSCI driver was introduced in Zephyr it was designed to rely on
a very PSCI-centric subsystem / interface.
There are two kinds of problems with this choice:
1. PSCI is only defined for the non-secure world and it is designed to
boot CPU cores into non-secure state (that means that PSCI is only
supposed to work if Zephyr is running in non-secure state)
2. There can be other ways or standards used to start / stop a core
different from PSCI
This patch is trying to fix the original wrong assumption by making the
interface / subsystem a generic one, called 'pm_cpu_ops', and using PSCI
only as an actual driver that is a user of this new interface /
subsystem.
For now the new subsystem is only exposing two methods: cpu_on and
cpu_off, others will probably follow according to the needs.
