[PATCH] Documentation: coding-style: Clean up header guard style

[Kieran Bingham]

Header guards were replaced by pragma once calls with commits
0a64cf8b7645 ("libcamera: Convert to pragma once") through to
796210ecea82 ("v4l2: Convert to pragma once")

Update the coding style to reflect the updated header guard style.
