c08b6a7037
This patch applies clang-format settings to most of tests files. Some files were fixed "by-hand" to exclude some lines, which whould be less readable after automatic style fixing. Moreover, some comments (mostly in tests/lib/edid-test.c) were adjusted to match coreboot coding style guidelines.
