Remove leading/trailing blank lines in .c, .h, .py, .rst, .yml, and .yaml files. Will avoid failures with the new CI test in https://github.com/zephyrproject-rtos/ci-tools/pull/112, though it only checks changed files. Move the 'target-notes' target in boards/xtensa/odroid_go/doc/index.rst to get rid of the trailing blank line there. It was probably misplaced.
