The USART or LPUART, especially on stm32wl, must set the EXTI
lines corresponding to the wakeUp source.
This LL_EXTI_LINE_xx is given by the Device Tree property.
This makes the system exiting lowpower stop mode on EXTI irq.
The LL_EXTI_LINE_x is exactly the bit(X) set.

The baudrate register (BRR) of a stm32 USART cannot be lower than 16.
The baudrate register (BRR) of a stm32 LPUART cannot be lower than 0x300
and greater than 0xFFFFF.
Add assertion to check the range.
This could be the case when configuring a baudrate of 9600 on usart
clocked by LSE (32768Hz).

Add emulator functionality to the serial_test driver, so that it can be
used to simulate a device on the other end of the uart.
If you don't set the buffer-size property in the dts node, there should
be effectively no change from the previous behavior.

According to i.MX RT1060 Reference Manual:
While the OR flag is set, no additional data is stored in the data
buffer even if sufficient room exists. To clear OR, write logic 1 to
the OR flag.
Clear OR (Overrun) flag whenever it is set, so that data continues to be
received after potential data overrun.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

When dealing with pm action 'suspend', driver applies device pinctrl sleep
state.
Using PM_DEVICE modes should allow to save more current consumption, and
applying pinctrl sleep state is one of the gains, but sleep state not being
available on a device is not a sufficient reason to block PM transition
to lower power mode.
If this pin state is not provided for the device, warn but don't block
pm transition. This will save some time to users setting up this feature
for the first time. Warning will give the opportunity to users to fine
tune their setup in a later step.

The LPUART driver activates the "noise" error interrupt but
neglects to clear the error bit when the interrupt occurs. This
causes the device to freeze. Clear the "noise" status to avoid
the lockup and track instances of this as a UART_ERROR_PARITY.
