This adds GPIO driver for Renesas SmartBond(tm) family.
Driver supports pin configuration (input/output) and interrupts on edge.
Interrupts on level are not supported by hardware.

Current implementation misses disabling input/output mux
once GPIO has already been configured. It means that after 1st
configuration, if GPIO is reconfigured, it won't disable previous
definitions, causing unexpected behavior.

Change Summary:
- Updating GPIO_CFG_IRQ define to enable multiple interrupts to
accomodate for IP configuration where each pin when interrupted
can trigger CPU interrupt.
- Removing gpio_dw_unmask_int define as it is NO OP

Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).
Automated using:
```
perl -i -pe 's/const struct device \*(?!const)(.*)= DEVICE/const struct
device *const $1= DEVICE/g' **/*.c
```

Recent change to constify struct devices pointers introduced a

It is frequent to find variable definitions like this:
```c
static const struct device *dev = DEVICE_DT_GET(...)
```
That is, module level variables that are statically initialized with a
device reference. Such value is, in most cases, never changed meaning
the variable can also be declared as const (immutable). This patch
constifies all such cases.

Define a pin structure to carry the pin configuration elements
such as push/pull, opendrain, input/output, high/low.
This structure will give the gpio_flags_t to the gpio_stm32_get_config.

In update the Kconfig to depend on devicetree, the SAM4L
driver was missing a 'default y'.
Also remove unnecessary 'depends on GPIO'.

Inside gpio_nrfx_pin_interrupt_configure, the "ch" variable is allocated
inside the "if", but then it gets dereferenced and the pointer saved in
trigger_config, which is used in the outer context.
This works fine right now, but that memory location could possibly be
reused by another automatic variable if the code gets changed.
Moving it in the function context to avoid any potential problem.

Now that we have 8 bits reserved for vendor specific GPIO flags,
introduce a new set of flags for nRF platforms to configure pins drive
mode. These new flags are equivalent to the previous existing ones, but
use a naming scheme the fits better with vendor hardware capabilities.
The table below shows the equivalence between old and new flag
| Old flags | New flags |
|---------------------------|-----------------------|
| `NRF_GPIO_DS_DFLT_LOW` | `NRF_GPIO_DRIVE_S0` |
| `NRF_GPIO_DS_DFLT_HIGH` | `NRF_GPIO_DRIVE_S1` |
| `NRF_GPIO_DS_ALT_LOW` | `NRF_GPIO_DRIVE_H0` |
| `NRF_GPIO_DS_ALT_HIGH` | `NRF_GPIO_DRIVE_H1` |
| `NRF_GPIO_DS_DFLT` | `NRF_GPIO_DRIVE_S0S1` |
| `NRF_GPIO_DS_ALT` | `NRF_GPIO_DRIVE_H0H1` |
| `NRF_GPIO_DS_DFLT_LOW \|` | `NRF_GPIO_DRIVE_S0H1` |
| `NRF_GPIO_DS_ALT_HIGH` | |
| `NRF_GPIO_DS_ALT_LOW \|` | `NRF_GPIO_DRIVE_H0S1` |
| `NRF_GPIO_DS_DFLT_HIGH` | |
Documentation has been written to explain in more detail the meaning of
the flags and how they can be used.
