Add multi-device support in npcx adc driver since there is more than one
adc module in npcx4 series. And each adc's reference voltage might be
different, this CL introduces the `vref-mv` prop. to select its own
reference voltage.

This change allows to have GPIO interrupts configured
that will work while chip enters low power modes where
PD_COM is turned off.
PDC controller can wake up system on GPIO changes even when
PD_COM is off.
This is done by adding PDC entries that will wakeup Cortex-M33
at the same time when WAKEUP controller is programmed to
handle GPIO state changes.

Previously the pwm capture only support capturing on channel 1
and 2, because the slave mode controller was used, which uses
the signal TIxFP which is not available for channel 3 and 4.
This commit adds optional support for four channel capturing by
changing the method of capturing PWM signals to not use the
slave mode controller to reset the counter register. Instead the
counter is reset in the ISR. This will result in a slight loss
of accuracy but is still within an acceptable range.

This introduces PWM driver with supporting PWM output
APIs based on NXP S32 EMIOS peripheral. This supports
three mode: OPWFMB, OPWMCB and OPWMB.
OPWFMB uses internal counter, the new period and duty
cycle takes effect immediately.
OPWMCB and OPWMB use external counter as timebase, changing
PWM period at runtime will impact to all channels share the

This commit improves the usage of the bus pipe (connected
to UART) to only open it when the modem is actually
powered and ready, not when leaving the idle state. This
ensures the pipe is flushed before sending the init script,
and re-enables the UART driver if it is disabled due to
errors.
While building a test platform based on the nRF9160 and a
Quectel BG95, it was discovered that the nRF9160 correctly
throws UART errors if the RX is enabled while the UART RX
line is low (which was due to the modem being powered
down).
The improvements should also help help remove the
"<wrn> modem_chat: receive buffer overrun" warning which
would occur during startup as the pipe was opened, but
nothing was receiving the data, causing the buffer to
overflow.

`CONFIG_BT_L2CAP_TX_MTU` drives the maximum supported MTU on a Bluetooth
connection, but the SPI backend also imposes its own hidden limits.
Display a warning if a value is chosen that can result in failures to

ranges on that symbol are already defined in terms of software features,
which would conflict with this check.

Only statements can be labeled in C, a declaration is not valid. This is
an FAQ.
While compilers currently in use don't seem to care, the "sparse" static
analyzer complains loudly (and cryptically):
https://github.com/thesofproject/sof/actions/runs/6052920348/job/16427323549
```
drivers/dma/dma_intel_adsp_hda.c:190:17: error: typename in expression
drivers/dma/dma_intel_adsp_hda.c:190:26: error: Expected ; at end of stmt
drivers/dma/dma_intel_adsp_hda.c:190:26: error: got rp
```
Add an empty ";" statement after each label makes `sparse` and probably
others happy.
Also add missing `const` to constants for clarity.

Modify the signature of the k_mem_slab_free() function with a new one,
replacing the old void **mem with void *mem as a parameter.
The following function:
void k_mem_slab_free(struct k_mem_slab *slab, void **mem);
has the wrong signature. mem is only used as a regular pointer, so there
is no need to use a double-pointer. The correct signature should be:
void k_mem_slab_free(struct k_mem_slab *slab, void *mem);
The issue with the current signature, although functional, is that it is
extremely confusing. I myself, a veteran Zephyr developer, was confused
by this parameter when looking at it recently.
All in-tree uses of the function have been adapted.
