NXP LPUART IP supports rs485 mode when transceiver driver enable
using RTS. Allow setting rs485 mode up via the "nxp,rs485-mode"
dts property. "nxp,rs485-de-active-low" dts property can be used
for set RTS polarity.

This commit is optimizing the uart isr execution to avoid starting
the Rx timeout if it is null. In anycase the async_timer_start
function is checking the tiemout value. This will just save some
execution lines.

Since the macro references `data->async->hw_rx_counting`, it cannot
be called when `data->async` is NULL, and this could happen when the
PM_DEVICE_ACTION_RESUME action was requested for an instance that uses
the interrupt-driven API while for another instance that uses the
asynchronous API the hardware counting of bytes was configured.
Prevent this by calling the macro from a proper `if` block.

rpi-hal function "uart_set_format" expects data width in the range
of 5..8. So I created a new function “uart_rpi_set_format” which
contains common parts of “uart_rpi_configure”.

Currently, uart_npcx_pm_policy_state_lock* functions are guarded by
CONFIG_UART_INTERRUPT_DRIVEN && CONFIG_PM. However, it is unnecessary to
guard them with CONFIG_UART_INTERRUPT_DRIVEN as the polling mode UART
driver also uses these functions.
This commit removes it and leaves those functions guarded by CONFIG_PM
only.

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.

This could be the case when configuring a baudrate of 9600 on usart

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.
