Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

These have been replaced by the appropriate call to
gpio_pin_interrupt_configure(). While the disable function could be
implemented using the new functionality, the enable function cannot
because the interrupt mode is not available. Consequently we cannot
replace these with equivalent functionality using the legacy API.
Clean up the internal implementation by removing the inaccessible
port-based enable/disable feature, leaving the pin-based capability in
place.

Add the common config structure as a prefix of the driver-specific
config structure. This driver uses fixups to define a common name
based on the SOC series; until aliases for the new properties are
added the code assumes all pins are supported.
Since pin ordinal validation is now done directly in gpio API,
remove checks inside the driver itself.

stm32_exti_enable was returning errors on line > 32 or line pointing
to non implemented line. Both conditions are hard-coded, hence there
is no use to detect them dynamically in the code.
Check them with assert. As a consequence, function could now be void.
Additionally, enable exti irq line only if both checks are passed.

Since it is now possible to disable/re-enable interrupts and
also to reconfigure an already configured interrupt, it is
now required to clear non requested triggers.
While it is not strictly requested, triggers are also cleared
when interrupt is disabled (assuming trigger should be configured
when interrupt is enabled).

Up to now interrupts could be only configured once, with no way to
disable them in runtime.
Allow interrupts to be disabled in runtime and then properly reenabled
on user request. This allows to ignore interrupts when software is not
expecting them.
The improvement over previously reverted patch [1] is that we disable
interrupts only when we configure port for which interrupt line was
previously selected. This for example prevents to disable interrupts
line 2 in case PA2 was previously configured as interrupt source, but we
are currently configuring PB2 as output.

Behavior of function gpio_stm32_configure has been modified
during driver factorization. Various gpio settings (speed, mode, ..)
are applied conditionally while they used to be applied in sequence,
unconditionally before this change. As a consequence some
combinations of configurations are no more applied (like speed for
alternate mode). This of course has impact in some use cases.
Rework functions in order to apply settings unconditionally. Take
advantage of the change to reduce code size.
This change impacts all SoCs except F1 series.
