Gerard Marull-Paretas a5fd0d184a init: remove the need for a dummy device pointer in SYS_INIT functions
The init infrastructure, found in `init.h`, is currently used by:

- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices

They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:

```c
struct init_entry {
	int (*init)(const struct device *dev);
	/* only set by DEVICE_*, otherwise NULL */
	const struct device *dev;
}
```

As a result, we end up with such weird/ugly pattern:

```c
static int my_init(const struct device *dev)
{
	/* always NULL! add ARG_UNUSED to avoid compiler warning */
	ARG_UNUSED(dev);
	...
}
```

This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:

```c
static int my_init(void)
{
	...
}
```

This is achieved using a union:

```c
union init_function {
	/* for SYS_INIT, used when init_entry.dev == NULL */
	int (*sys)(void);
	/* for DEVICE*, used when init_entry.dev != NULL */
	int (*dev)(const struct device *dev);
};

struct init_entry {
	/* stores init function (either for SYS_INIT or DEVICE*)
	union init_function init_fn;
	/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
	 * to know which union entry to call.
	 */
	const struct device *dev;
}
```

This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.

**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Gerard Marull-Paretas e81e92dbb9 boards: convert images to JPEG and reduce image size
The boards folder uses ~142.8 MB, being the largest in the repository.
This is due mostly to board images, which are in most cases not
optimized for web content. This patch tries to address this problem by
converting all pictures to JPEG (quality 75) and by adjusting its size
up to 750 px (the width of the documentation content). Images that
specified a fixed width in rst files are converted down to that value
instead.

With this patch, folder goes down to ~53.5 MB from 142.8 MB (-~63%).
Note that this patch introduces a new set of binary files to git
history, though (bad).

The process has been automated using this quickly crafted Python script:

```python
from pathlib import Path
import re
import subprocess

def process(doc, image, image_jpeg, size):
    subprocess.run(
        (
	     f"convert {image}"
	     "-background white -alpha remove -alpha off -quality 75"
	     f"-resize {size}\> {image_jpeg}"
	),
        shell=True,
        check=True,
        cwd=doc.parent,
    )
    if image != image_jpeg:
        (doc.parent / image).unlink()

for doc in Path(".").glob("boards/**/*.rst"):
    with open(doc) as f:
        content = ""
        image = None
        for line in f:
            m = re.match(r"^(\s*)\.\. (image|figure):: (.*)$", line)
            if m:
                if image:
                    process(doc, image, image_jpeg, size)

                image = Path(m.group(3))
                if image.suffix not in (".jpg", ".jpeg", ".png"):
                    content += line
                    image = None
                    continue

                image_jpeg = image.parent / (image.stem + ".jpg")
                size = 750
                content += (
                    f"{m.group(1)}.. {m.group(2)}:: {image_jpeg}\n"
                )
            elif image:
                m = re.match(r"\s*:height:\s*[0-9]+.*$", line)
                if m:
                    continue

                m = re.match(r"\s*:width:\s*([0-9]+).*$", line)
                if m:
                    size = min(int(m.group(1)), size)
                    continue

                content += line
                if line == "\n":
                    process(doc, image, image_jpeg, size)
                    image = None
            else:
                content += line

    with open(doc, "w") as f:
        f.write(content)

Gerard Marull-Paretas ada8d72888 boards: remove non-minimal peripherals from defconfig
According to the board porting guidelines, boards should "leave
peripherals and their drivers disabled by default". In Zephyr we
tipically enable GPIO and SERIAL, as they are virtually required by all
samples/tests in tree. However, for the rest of peripherals it is up to
the application/test to enable the necessary driver classes. It is also
useful that board's Kconfig.defconfig enables certain driver peripherals
based on a condition, e.g. enable I2C if SENSOR=y.

Ref. https://docs.zephyrproject.org/latest/hardware/porting/
board_porting.html#general-recommendations

This patch removes the following driver classes from defconfig files:

- CONFIG_ADC
- CONFIG_COUNTER
- CONFIG_EEPROM
- CONFIG_ENTROPY
- CONFIG_ESPI
- CONFIG_HWINFO
- CONFIG_I2C
- CONFIG_LED
- CONFIG_NETWORKING
- CONFIG_PS2
- CONFIG_PWM
- CONFIG_SENSOR
- CONFIG_SPI
- CONFIG_SPI_SLAVE
- CONFIG_WATCHDOG

Now that serial drivers are enabled based on devicetree we can remove
any cases of them getting enabled by *defconfig and proj.conf files.

Kumar Gala 600d749cf3 gpio: remove Kconfig.defconfig setting of GPIO drivers
Now that gpio drivers are enabled based on devicetree
we need to remove any cases of them getting enabled by
Kconfig.defconfig* files as this can lead to errors.

Typically the Kconfig.defconfig* will blindly enable a
sensor and not respect the devicetree state of the GPIO.
Additionally we can get problems with prj.conf/defconfig
getting incorrectly overridden.

Kumar Gala 762eadc15d drivers: gpio: dw: rework init to use DT_INST_FOREACH_STATUS_OKAY
Use DT_INST_FOREACH_STATUS_OKAY to reduce duplicated code for each
instance.

We make interrupts optional since they aren't always available.
