The gpio_pca953x gpio driver doesn't have
the input latch and interrupt mask
configuration which causes a lack of accessing
and using those features on an gpio expander
device. Fix it by adding input latch and
interrupt mask configurations in this driver.

For the Ambiq Apollo4x soc, every 32 pins share the same IRQ
number. irq_disable() should not be called for the pin interrupt
disablement, otherwise the interrupt of pins in the same GPIO
group will be disabled as well.

Use gpio toggle api instead of manually toggling.
Remove redundant text.
Print error and break from blinking if it occurs.
Only print 'how to exit' text if first toggle is successful.
Saves roughly 40 bytes.

Usage:
gpio info [device]
The new command prints gpio controller information
for a specific device if specified or if no device is specified
it prints out all controller information ordered by line name.
Also added Kconfig option so this command can be removed if
resources need to be conserved.

This commit implements this enhancement:
https://github.com/zephyrproject-rtos/zephyr/issues/63018
The forms of the gpio commands are now:
gpio conf device pin ol0
gpio set device pin 1
gpio get device pin
gpio blink device pin
Device name and pin subcommands now are
suggested/completed when tab is used.
Pin names are suggested with numbers and line names if
available from the gpio controller’s Devicetree node.
GPIO pin command is now limited to pins that are not assigned
as reserved.

The multi-level encoding of the interrupt number currently
happens in the `gen_defines.py`, which is called in the
`dts.cmake` module after `kconfig.cmake`. However, the number
of bits used by each level is defined in Kconfig and this means
that `gen_defines.py` will not be able to get that information
during build.
To fix this, do the multi-level encoding in C devicetree macro
magic instead of the python script. This ticks one of a
long-standing TODO item from the `gen_defines.py`.

Relocate multi-level interrupts APIs out of `irq.h` into

separation between typical irq & multilevel ones.
Added preprocessor versions of `irq_to_level_x` as `IRQ_TO_Lx`.

Extend the NXP S32 GPIO driver to be able to route external interrupts
to either SIUL2 EIRQ interrupt controller or, when available on the
SoC, WKPU interrupt controller.
Since WKPU can support up to 64 external interrupt sources and SIUL2
EIRQ up to 32, gpio_get_pending_int() is removed and the interrupt
controller specific API must be used instead.

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.

Current setup tries to initialize the bank driver before the parent one,
which is the inverse of what the devicetree hierarchy implies and
causes a bunch of:
ERROR: /soc/gpio@e000a000/psgpio_bank@3 PRE_KERNEL_1 40 32 <
/soc/gpio@e000a000 PRE_KERNEL_2 40 10
Change the bank driver to initialize at PRE_KERNEL_1 as the parent
drivers so that ordinals take care of priority between these two.
