The current implementation requires SoCs/Boards to manualy instantiate
the preripherals and initilize them.
The change lets Zephyr rely on the device tree setup to instantiate &
initialize the relevant gpio peripheral.

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.

Reorder gpio_rpi_configure to disable input buffers when not in use.
gpio_rpi_get_config can then determine whether a pin is configured as an
input without requiring additional state variables, as well as reducing
input leakage current.

Out of reset the pads are input enabled, output disabled. Disconnect the
pad's input and output buffers, as well as any pullups. This can reduce
input leakage current.

In the current implementation, when `gpio_ra_pin_interrupt_configure`
is executed, the existing settings made by `gpio_ra_pin_configure`
are erased.
A read-modify-write method will be used to preserve the settings.

The reset pulse is currently fixed at 1 µs, the minimum required for
the chip. However, a long reset pin trace can increases rise time, making
1 µs potentially insufficient for reliable detection of a reset signal.
Increase the pulse duration to 2 µs

Refactor and merge the SoC support files for the Atmel SAM E70 and SAM V71
product series. These SoCs are part of a larger product family (SAM
E70/S70/V70/V71) and share a common set of peripherals.
Support for the two remaining product series (SAM S70/V70) is not part of
this refactoring as these will require further additions to the Atmel HAL.

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

Set up a named device MMIO memory mapping in the GPIO controller's
parent device, map the virtual memory in the init function of the
parent device.
Once the controller's register space has been successfully mapped,
propagate the mapped virtual address to all child (= GPIO bank)
devices. While it is possible to add a named mapping to every
single GPIO bank device and initialize it in the respective bank
device's init function, this would result in multiple virtual
address mappings all pointing to the same 4k of physical memory.
I assume that, although all those mappings having the same attri-
butes, such a setup is at least discouraged.

Implemented diagnostic functionality for all 8 channels
which include various check to over/under voltage and wire break.
Filtering configuration is done from devicetree on per channel
bases and is configured on chip start.
In case some fault condition occure FAULT pin drive LOW which
