The GCR, PINCTRL, I2C and WUC registers of the it82xx2 will be remapped,
so these device nodes will not be in the it8xxx2.dtsi, these should be
separated to create a it81xx2.dtsi.

hal_espressif systimer HAL calls are based on 1MHz reference.
This changes systimer driver to allow max clocking reference of 16MHz
and increases soc tick resolution by reducing min delay interval.
This also sets all ESP32-C3 socs to 16MHz hardware cycles reference.

This commit disables testing for the `tlsr9518adk80d` platform because
it contains an invalid linker script (overlapping memory region) and
cannot be compiled using the current version of the Zephyr SDK (0.15.0
at the time of making this change).
Revert this commit to re-enable testing for this platform once the
GitHub issue #49036 is fixed.

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)

Adding I2C FIFO mode can reduce the time between each byte to
improve the I2C bus clock stretching during I2C transaction.
The I2C master supports two 32-bytes FIFOs, channel A and C
are supported now.
I2C FIFO mode of it8xxx2 can support I2C APIs including:
i2c_write(), i2c_read(), i2c_burst_read.
Test:
1. tests\drivers\i2c\i2c_api --> pass
2. Reading 16 bytes of data through i2c_burst_read() can reduce
0.52ms(2.4ms->1.88ms) compared to the original pio mode when the
frequency is 100KHz.
3. It is normal to read sensor data through I2C on Nereid's platform.

:envvar: is currently used to tag environment variables, however,
:envvar: role expects a matching .. envvar:: directive where the
environment variable is defined. This patch fixes some cases by adding
envvar directives and by converting certain cases to literals (it
doesn't make sense to document all env vars in a list, as some are
self-documented by contextual information).
