The problem is that net_if_call_timestamp_cb only checked if the
callback was registered for the PORT which invoked the whole action.
There is a possibility, that the callback will be registered, and packet
A will be passed to eth driver. Before the driver is finished with
packet A, network layer will start handling another packet (B) - so it
will unregister the callback for packet A and register it for B. After
that the network driver will finish processing packet A and invoke the
timestamp callback. The mechanism would then only check if a callback is
registered for the port of the driver and invoke the callback for the
packet that was registered earlier (so A instead of B).
This commit fixes that by storing info not only about the port but about
the packet too.

This commit refactors internal functions in arm_mpu.c to use
bitsets and functions taken directly from ARM CMSIS instead of
hardcoded arithmetic literals. In several internal functions
some part of the implementation is abstracted further in inline
functions or convenience macros, to facilitate extending the
arm_mpu.c for ARMv8-M. In addition, the commit adds minor
improvements in internal function documentation.

This patchs adds new I2C Syscalls for :
- I2C controllers slave support
- I2C Slave drivers support
I2C Controllers slave support adds 2 new ops to :
- register new slave driver
- unregister slave driver
Slave funcs consists on all the I2C phases :
- read or write request once address matches
- read or write done once the byte has been received/sent
- stop when the trasmit stops
I2C Slave drivers syscall are also added to make new
"I2C Slave" drivers to :
- register them to their I2C controller
- unregister them to their I2C controller

This commit moves the _ms_to_ticks() and __ticks_to_ms() functions

The kernel incorrectly assumed, that system timer frequency is always
divisible without remainder by couple "natural" tick rates (like 100).
As result on some SoCs, time calculations was not correct, producing
strange effects (invalid sleep times, incorrect k_uptime_get() etc.).
This commit enables accurate, but costly (using 64-bit math) tick <-> ms
conversion if the selected tick interval is not exact due to hardware
limitations.
Also, this commit fixes tests in which removed _ms_per_tick were used.

Zephyr 1.12 removed the old scheduler and replaced it with the choice
of a "dumb" list or a balanced tree. But the old multi-queue
algorithm is still useful in the space between these two (applications
with large-ish numbers of runnable threads, but that don't need fancy
features like EDF or SMP affinity). So add it as a
CONFIG_SCHED_MULTIQ option.

* We are now *much* better at not reserving unnecessary
system MPU regions based on configuration. The #defines
for intent are now an enumerated type. As a bonus, the
implementation of _get_region_index_by_type() is much
simpler. Previously we were wasting regions for stack guard
and application memory if they were not configured.
* NXP MPU doesn't reserve the last region if HW stack
protection isn't enabled.
* Certain parts of the MPU code are now properly ifdef'd
based on configuration.
* THREAD_STACK_REGION and THREAD_STACK_USER_REGION was a
confusing construction and has now been replaced with
just THREAD_STACK_REGION, which represents the MPU region
for a user mode thread stack. Supervisor mode stacks
do not require an MPU region.
* The bounds of CONFIG_APPLICATION_MEMORY never changes
and we just do it once during initialization instead of
every context switch.
* Assertions have been added to catch out-of-bounds cases.

Console subsystem is intended to be a layer between console drivers
and console clients, like e.g. shell. This change factors out code
from shell which dealed with individial console drivers and moves it
to console subsystem, under the name console_register_line_input().
To accommodate for this change, older console subsys Kconfig symbol
is changed from CONFIG_CONSOLE_PULL to CONFIG_CONSOLE_SUBSYS
(CONFIG_CONSOLE is already used by console drivers). This signifies
that console subsystem is intended to deal with all of console
aspects in Zephyr (existing and new), not just provide some "new"
functionality on top of raw console drivers, like it initially
started.

Set Zero Latency IRQ to priority level zero and SVCs to priority level
one when Zero Latency IRQ is enabled.
This makes Zero Zatency truly zero latency when the kernel has been
configured with userspace enabled, or when IRQ offloading is used.
Exceptions can still delay Zero Latency IRQ, but this is considered
ok since exceptions indicate a serious error, and the system needs to
recover.

Instead of finding the address of the spurious irq function in the
intList section we now rely on the linker to find the address in the
_irq_spurious symbol.
This is a migration from using code generation to using the C language
which we in the general case we should aways strive towards.
In this specific case it makes the generated code 'irq_tables.c'
easier to read as we replace magic numbers with the &_irq_spurious
token.
Also, the path through the build system that _irq_spurious makes is
much shorter, so it is much easier for a user to understand how it is
used.
