Zephyr GPIO drivers require the pin mask `struct gpio_driver_data` to be
the first element of the driver config. Reordering fixes failures in ASSERT
statements of the GPIO driver due to the base address being interpreted as
supported pin mask.

As the RP2350B has more than 32 GPIO pins,
we changed the configuration so that it is split into two ports.
To do this, we created a `raspberrypi,pico-gpio-port` node and
moved the previous `raspberrypi,pico-gpio-port` functions to it.
This became a child node of `raspberrypi,pico-gpio-port`, and
`raspberrypi,pico-gpio-port` will remain a gpio mapper.

Update the NEORV32 SoC, peripheral drivers, and board to support NEORV32
v1.11.1. Notable changes include:
- Optional RISC-V ISA Kconfigs are now selected on the board level.
- Peripheral registers are now automatically reset in hardware, no need for
software initialization code.
- The NEORV32 GPIO controller now supports 32 pins, not 64. Interrupt
support will be submitted in a separate PR.
- Default board configuration has 64k RAM and is clocked at 18 MHz.

The ADP5585_GPO_OUT_MODE_A is used when configuring initial output
during pin configuration, causing pins configured HIGH is incorrectly
configured as open-drain. Replacing the reg with ADP5585_GPO_DATA_OUT
fixes the issue.

Streamline code in multiple places as follows:
- Remove redundant initialization of `ret` to `0`,
as it is immediately assigned a value.
- Add `len` to store the result of `strlen(argv[ARGV_CONF])` to avoid
multiple calls to `strlen` within the `for-loop` in `cmd_gpio_conf`.
- Merge separate `shell_print` calls by including a newline `\n`.

Use the first nodelabel rather than the node name when available for
shell completion as well as "gpio info". This label is always set gpio
nodes as that's what's used for references by device nodes, there may be
some case where a node has multiple labels for some reason but for a
human I reckon it still makes more sense to suggest a label rather than
the address.
This means that the commands would use, for example "gpioa" rather than
"gpio@58020000".
Fall back to the normal node name if there's no label set or if dt
metadata is not enabled.

Add driver support for Versal Gen 2 PS/PMC GPIO controller by updating
the logic of bank index calculation.
This logic depends on "register" DT property to identify bank index
instead of depending on node instance ID as Versal Gen 2 GPIO banks
are not in sequential order as Zynqmp.
- Versal Gen 2 PS GPIO: Banks(0,3,4)
- Zynqmp PS GPIO: Banks(0,1,2,3,4,5)

Implement the `gpio_get_config`
N.b. adding this API results in a new test failure in
`test_gpio_config_trigger`. This suggests that there is some kind of
dependency between this and the now-enabled `pin_get_config` test cases.
Note that this adds a read-only API, it is unlikely to be the cause of
the failure.

gpio_rpi_get_config can then determine whether a pin is configured as an
