This commit rebrands the STM32 EXTI API to a more hardware-agnostic
"GPIO interrupt controller" API, in anticipation of the introduction of
new series lacking the EXTI peripheral. The GPIO and EXTI drivers are
updated to match the rebranded API.

This commit makes the contents of the stm32_exti_line_t data type opaque to
the EXTI GPIO interrupt controller API users. The GPIO driver is updated
to comply with this API change.
N.B.: while some assertions are removed as part of this commit, they were
broken since forever anyways, so nothing of value is lost.

- Removed zero initialization of `pincfg` structure as all members
are guaranteed to be set.
- Introduced `pfs_cfg` as an intermediate variable to store data in
the CPU register instead of stack.
- Simplified pin setting logic by relying on `pfs_cfg` being
zero-initialized, eliminating the need for explicit bit clearing.

Using DEVICE_DEFINE, a device without a corresponding DT node can be
defined (for example CRYPTO_MTLS), Z_DEVICE_INIT() does not initialize
dt_meta for such devices, leaving the field as NULL.
device_get_dt_nodelabels() and functions calling it have to handle
dev->dt_meta == NULL to prevent fatal errors.

A wrong bit mask (wrong: IOMUXC_SW_PAD_CTL_PAD_PUS_MASK = 0x8) was used.
That bit mask is for PUE/PUS-type gpio registers, but this is the

LPC GPIO binding was wrong in that the reg address
on the simple soc bus was given as an index of the gpio ports
within a gpio controller. Fix this by putting the GPIO node
on the simple bus as a single node with the correct base address,
and make the ports children of this node.
Change the driver to get the port number from the reg address
instead of a custom property, and get base address from DT instead
of the SDK macro definition.

Use some new kernel features to make the experience of finding and
dealing with GPIO devices much more ergonomic by allowing the use of
devicetree node labels to identify GPIO devices by default.
Users who wish to avoid the associated footprint penalty can set
CONFIG_DEVICE_DT_METADATA=n by hand, but I think the convenience is
worth the price as a default. If we're running a shell, then we've
already paid a heavy footprint penalty.
