In order to bring consistency in-tree, migrate all samples to the use
the new prefix <zephyr/...>. Note that the conversion has been scripted:
```python
from pathlib import Path
import re
EXTENSIONS = ("c", "h", "cpp", "rst")
for p in Path(".").glob("samples/**/*"):
if not p.is_file() or p.suffix and p.suffix[1:] not in EXTENSIONS:
continue
content = ""
with open(p) as f:
for line in f:
m = re.match(r"^(.*)#include <(.*)>(.*)$", line)
if (m and
not m.group(2).startswith("zephyr/") and
(Path(".") / "include" / "zephyr" / m.group(2)).exists()):
content += (
m.group(1) +
"#include <zephyr/" + m.group(2) +">" +
m.group(3) + "\n"
)
else:
content += line
with open(p, "w") as f:
f.write(content)
