clk: tests: Add test suites description 

JIRA: https://issues.redhat.com/browse/RHEL-5705

    clk: tests: Add test suites description

    We start to have a few test suites, and we'll add more, so it will get
    pretty confusing to figure out what is supposed to be tested in what
    suite.

    Let's add some comments to explain what setup they create, and what we
    should be testing in every suite.
