tests: Fix tests code and comments style

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.
