    clocksource: Use pr_info() for "Checking clocksource synchronization" message

    The "Checking clocksource synchronization" message is normally printed
    when clocksource_verify_percpu() is called for a given clocksource if
    both the CLOCK_SOURCE_UNSTABLE and CLOCK_SOURCE_VERIFY_PERCPU flags
    are set.

    It is an informational message and so pr_info() is the correct choice.
