Add the pinctrl state name (default) for the UART/USART/LPUART
peripherals. Changes performed using the following Python script run
from the repository root:
```
from pathlib import Path
import re
for fpath in Path(".").glob("boards/arm/**/*.dts"):
lines = open(fpath).readlines()
is_stm32 = False
for line in lines:
if "stm32" in line:
is_stm32 = True
break
if not is_stm32:
continue
with open(fpath, "w") as f:
for line in lines:
f.write(line)
m = re.match(r"(\s+)pinctrl-0.*us?art.*", line)
if m:
f.write(m.group(1) + "pinctrl-names = \"default\";\n")
```

When I added this board recently I mistakenly placed
the Arduino SCL pin (Default Zephyr pin) as PB6
when it should be PB8.
The SPI node is now properly set to SPI2 peripheral
instead of SPI1. SPI2 is the most suitable to follow
the silkscreen on the printed circuit board.
Added arduino_gpio to yaml.
