The toplevel adc_seq_table is now copied onto the stack and
the stack copy used.
The contained entries array is now copied onto an allocation
drawn from the caller's resource pool, to prevent modification
of the buffer pointers.
The return value policy here is to oops the caller if bad memory
or objects are passed in, but return an error otherwise.
Based on an original patch by Leandro Pereira, rebased and the
copy of the entries array added.

The various macros to do checks in system call handlers all
implictly would generate a kernel oops if a check failed.
This is undesirable for a few reasons:
* System call handlers that acquire resources in the handler
have no good recourse for cleanup if a check fails.
* In some cases we may want to propagate a return value back
to the caller instead of just killing the calling thread,
even though the base API doesn't do these checks.
These macros now all return a value, if nonzero is returned
the check failed. K_OOPS() now wraps these calls to generate
a kernel oops.
At the moment, the policy for all APIs has not changed. They
still all oops upon a failed check/
The macros now use the Z_ notation for private APIs.

Add driver for MCUX mailbox which can be used for lpcxpresso54114

The mcux sim clock control driver was originally designed to pass
through the clock subsystem value from dts to the mcux CLOCK_GetFreq()
function. This assumed that the values in
include/dt-bindings/clock/kinetis_sim.h matched the enumeration in
fsl_clock.h, which is true for the coresys, platform, and bus clocks.
However, the low-power oscillator (LPO) clock has a different values in
k64 vs. kw2xd, therefore we must update the clock_control driver to
parse the value from dts and convert it to the fsl_clock.h enumeration.

TimerHandle->Init.Period is used to initialize TIMx ARR register. The
timer will count from 0 up to ARR including, thus it will tick
(ARR + 1) timers per period. As the "period_cycles" variable holds the
number of desired ticks, the ARR register is computed as
ARR = period_cycles - 1
Update the code to reflect this relationship. Otherwise the timer will
count one more tick for each period, leading to a wrong PWM frequency.

Fix a somewhat rare race condition when the thread gets
preempted in the middle of sending a byte through UART.
If the other thread also sends another byte through UART
and "consumes" the EVENTS_TXDRDY value, the first thread
will get stuck in the while loop forever.
By moving the reset to the function start, we guarantee that
the baseline state of EVENTS_TXRDY is 1. Therefore, the first
thread will continue normally when it executes again.

Normally a syscall would check the current privilege level and then
decide to go to _impl_<syscall> directly or go through a
_handler_<syscall>.
__ZEPHYR_SUPERVISOR__ is a compiler optimization flag which will
make all the system calls from the driver files directly link
to the _impl_<syscall>. Thereby reducing the overhead of checking the
privileges.
In the previous implementation all the source files would be compiled
by zephyr_source() rule. This means that zephyr_* is a catchall CMake
library for source files that can be built purely with the include
paths, defines, and other compiler flags that all zephyr source
files uses. This states that adding one extra compiler flag for only
one complete directory would fail.
This limitation can be overcome by using zephyr_libray* APIs. This
creates a library for the required directories and it also supports
directory level properties.
Hence we use zephyr_library* to create a new library with
macro _ZEPHYR_SUPERVISOR_ for the optimization.
