Subject: [PATCH v4 1/2] 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() should be used
instead of pr_warn().
