update gpio driver to adapt rt7xx gpio model:
1. There is no PORT_Type on RT7xx,so set PORT_Type as void
2. Add port_no parameter in gpio_mcux_config to adapt IOPCTL driver
3. Add gpio-port-offest parameter in blinding, it will help map the
relation between index n and gpio port when some soc have domain
access attribution.
3. Splite gpio_mcux_configure function into two functions(
gpio_mcux_iopctl_configure and gpio_mcux_port_configure)
according to CONFIG_PINCTRL_NXP_IOCON macro
4. Add code to adapt RT700 GPIO attribute configuration

Reserve the upper 8 bits of gpio_dt_flags_t for SoC specific flags and
move the non-standard, hardware-specific GPIO devicetree flags (IO
voltage level, drive strength, debounce filter) from the generic
dt-bindings/gpio/gpio.h header to SoC specific dt-bindings headers.
Some of the SoC specific dt-bindings flags take up more bits than
necessary in order to retain backwards compatibility with the deprecated
GPIO flags. The width of these fields can be reduced/optimized once the
deprecated flags are removed.
Remove hardcoded use of GPIO_INT_DEBOUNCE in GPIO client drivers. This
flag can now be set in the devicetree for boards/SoCs with debounce
filter support. The SoC specific debounce flags have had the _INT part
of their name removed since these flag must be passed to
gpio_pin_configure(), not gpio_pin_interrupt_configure().

Refactors all of the on-chip GPIO drivers to use a shared driver class
initialization priority configuration, CONFIG_GPIO_INIT_PRIORITY, to
allow configuring GPIO drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
Most drivers previously used CONFIG_KERNEL_INIT_PRIORITY_DEFAULT or
CONFIG_KERNEL_INIT_PRIORITY_DEVICE, therefore the default for this new
option is the lower of the two, which means earlier initialization.
Driver-specific options for off-chip I2C- or SPI-based GPIO drivers are
left intact because they often need to be initialized at a different
priority than on-chip GPIO drivers.

This commit removes API functions and macros which were deprecated in
2.2 release. GPIO drivers are updated accordingly.

Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.
Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.
To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:
- emit macros for all existing nodes in gen_defines.py, regardless
of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

Convert driver to use DT_INST_ defines. As part of this conversion we
remove the Kconfig options for per GPIO controller enables and instead
get that information from device tree. This means we now disable each
GPIO controller by default in the DTS and have each board dts enable the
GPIO controller ports it needs.

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.

Change when we clear interrupt status to happen before we handle the
callbacks. As the callbacks might manipluate the GPIO state and cause
a GPIO interrupt. If we clear interrupt status after than we might

Also only clear interrupts for interrupts that are we have enabled and
that were reported when we read from the interrupt status.

Some mcux gpio instances do not have dedicated interrupt vectors and
therefore conditionalize out the IRQ_CONNECT() and irq_enable() calls
during driver initialization. The driver initialization incorrectly
returned an error in this case, when really it just has nothing to do.
The driver can still be used without interrupts, and the gpio configure
function returns an error if an application tries otherwise.
Commit a68120de6d introduced a check on
the init return value to prevent applications from using drivers that
fail to initialize. This in turn caused zephyr/samples/basic/threads to
assert on the frdm_kl25z board. Fix this by modifying the mcux gpio
driver to return success when there is no interrupt to connect.
